e7e5878953 Avoid BeaconState clone during metrics scrape (#2298)
## Issue Addressed

Which issue # does this PR address?

## Proposed Changes

Avoids cloning the `BeaconState` each time Prometheus scrapes our metrics (generally every 5s 😱).

I think the original motivation behind this was *"don't hold the lock on the head whilst we do computation on it"*, however I think is flawed since our computation here is so small that it'll be quicker than the clone.

The primary motivation here is to maintain a small memory footprint by holding less in memory (i.e., the cloned `BeaconState`) and to avoid the fragmentation-creep that occurs when cloning the big contiguous slabs of memory in the `BeaconState`.

I also collapsed the active/slashed/withdrawn counters into a single loop to increase efficiency.

3d239b85ac Allow for a clock disparity on the duties endpoints (#2283)
## Issue Addressed

Resolves #2280

## Proposed Changes

Allows for API consumers to call the proposer/attester duties endpoints [`MAXIMUM_GOSSIP_CLOCK_DISPARITY`](b34a79dc0b/beacon_node/beacon_chain/src/beacon_chain.rs (L99-L102)) earlier than the current epoch.

03cefd0065 Expand observed attestations capacity (#2266)
## Issue Addressed

NA

## Proposed Changes

I noticed the following error on one of our nodes:

```
Mar 18 00:03:35 ip-xxxx lighthouse-bn[333503]: Mar 18 00:03:35.103 ERRO Unable to validate aggregate            error: ObservedAttestersError(EpochTooLow { epoch: Epoch(23961), lowest_permissible_epoch: Epoch(23962) }), peer_id: 16Uiu2HAm5GL5KzPLhvfg9MBBFSpBqTVGRFSiTg285oezzWcZzwEv
```

The slot during this log was 766,815 (the last slot of the epoch). I believe this is due to an off-by-one error in `observed_attesters` where we were failing to provide enough capacity to store observations from the previous, current and next epochs. See code comments for further reasoning.

Here's a link to the spec: https://github.com/ethereum/eth2.0-specs/blob/v1.0.1/specs/phase0/p2p-interface.md#beacon_aggregate_and_proof

f9d60f5436 VC: accept unknown fields in chain spec (#2277)
## Issue Addressed

Closes #2274

## Proposed Changes

* Modify the `YamlConfig` to collect unknown fields into an `extra_fields` map, instead of failing hard.
* Log a debug message if there are extra fields returned to the VC from one of its BNs.

This restores Lighthouse's compatibility with Teku beacon nodes (and therefore Infura)

9a71a7e486 Fix default implementation on FixedVector (#2264)
## Issue Addressed

NA

## Proposed Changes

Whilst hacking on something I noticed that the default implementation of `FixedVector` can violate the length constraint!

E.g., `let v: FixedVector<u8; U4> = <_>::default()` would create a fixed vector with length 0, even though it promises to *always* have length 4! This causes SSZ deserialization to fail and probably other things too.

This isn't a security risk as it can't be triggered externally, however it's a foot gun for LH devs.

015ab7d0a7 Optimize validator duties (#2243)
## Issue Addressed

Closes #2052

## Proposed Changes

- Refactor the attester/proposer duties endpoints in the BN
    - Performance improvements
    - Fixes some potential inconsistencies with the dependent root fields.
    - Removes `http_api::beacon_proposer_cache` and just uses the one on the `BeaconChain` instead.
    - Move the code for the proposer/attester duties endpoints into separate files, for readability.
- Refactor the `DutiesService` in the VC
    - Required to reduce the delay on broadcasting new blocks.
    - Gets rid of the `ValidatorDuty` shim struct that came about when we adopted the standard API.
    - Separate block/attestation duty tasks so that they don't block each other when one is slow.
- In the VC, use `PublicKeyBytes` to represent validators instead of `PublicKey`. `PublicKey` is a legit crypto object whilst `PublicKeyBytes` is just a byte-array, it's much faster to clone/hash `PublicKeyBytes` and this change has had a significant impact on runtimes.
    - Unfortunately this has created lots of dust changes.
 - In the BN, store `PublicKeyBytes` in the `beacon_proposer_cache` and allow access to them. The HTTP API always sends `PublicKeyBytes` over the wire and the conversion from `PublicKey` -> `PublickeyBytes` is non-trivial, especially when queries have 100s/1000s of validators (like Pyrmont).
 - Add the `state_processing::state_advance` mod which dedups a lot of the "apply `n` skip slots to the state" code.
    - This also fixes a bug with some functions which were failing to include a state root as per [this comment](072695284f/consensus/state_processing/src/state_advance.rs (L69-L74)). I couldn't find any instance of this bug that resulted in anything more severe than keying a shuffling cache by the wrong block root.
 - Swap the VC block service to use `mpsc` from `tokio` instead of `futures`. This is consistent with the rest of the code base.
    
~~This PR *reduces* the size of the codebase 🎉~~ It *used* to reduce the size of the code base before I added more comments. 

## Observations on Prymont

- Proposer duties times down from peaks of 450ms to consistent <1ms.
- Current epoch attester duties times down from >1s peaks to a consistent 20-30ms.
- Block production down from +600ms to 100-200ms.

## Additional Info

- ~~Blocked on #2241~~
- ~~Blocked on #2234~~

## TODO

- [x] ~~Refactor this into some smaller PRs?~~ Leaving this as-is for now.
- [x] Address `per_slot_processing` roots.
- [x] Investigate slow next epoch times. Not getting added to cache on block processing?
- [x] Consider [this](072695284f/beacon_node/store/src/hot_cold_store.rs (L811-L812)) in the scenario of replacing the state roots

```

The reason for this is that the condition was backwards, so that whole block of code was unreachable.

Looking at the attestations for the block included in the block after, we can see that lots of validators missed it. Some of them may be Lighthouse v1.1.1-v1.2.0-rc.0, but it's probable that they would have missed even with the proposer cache primed, given how late the block 708544 arrived (the cache miss occurred 3.787s after the slot start): https://beaconcha.in/block/708545#attestations

babd153352 Prevent adding and dialing bootnodes when discovery is disabled (#2247)
This is a small PR which prevents unwanted bootnodes from being added to the DHT and being dialed when the `--disable-discovery` flag is set. 

The main reason one would want to disable discovery is to connect to a fix set of peers. Currently, regardless of what the user does, Lighthouse will populate its DHT with previously known peers and also fill it with the spec's bootnodes. It will then dial the bootnodes that are capable of being dialed. This prevents testing with a fixed peer list.

This PR prevents these excess nodes from being added and dialed if the user has set `--disable-discovery`.

e4eb0eb168 Use advanced state for block production (#2241)
## Issue Addressed

NA

## Proposed Changes

- Use the pre-states from #2174 during block production.
    - Running this on Pyrmont shows block production times dropping from ~550ms to ~150ms.
- Create `crit` and `warn` logs when a block is published to the API later than we expect.
    - On mainnet we are issuing a warn if the block is published more than 1s later than the slot start and a crit for more than 3s.
- Rename some methods on the `SnapshotCache` for clarity.
- Add the ability to pass the state root to `BeaconChain::produce_block_on_state` to avoid computing a state root. This is a very common LH optimization.
- Add a metric that tracks how late we broadcast blocks received from the HTTP API. This is *technically* a duplicate of a `ValidatorMonitor` log, but I wanted to have it for the case where we aren't monitoring validators too.

363f15f362 Use the database to persist the pubkey cache (#2234)
## Issue Addressed

Closes #1787

## Proposed Changes

* Abstract the `ValidatorPubkeyCache` over a "backing" which is either a file (legacy), or the database.
* Implement a migration from schema v2 to schema v3, whereby the contents of the cache file are copied to the DB, and then the file is deleted. The next release to include this change must be a minor version bump, and we will need to warn users of the inability to downgrade (this is our first DB schema change since mainnet genesis).
* Move the schema migration code from the `store` crate into the `beacon_chain` crate so that it can access the datadir and the `ValidatorPubkeyCache`, etc. It gets injected back into the `store` via a closure (similar to what we do in fork choice).

afd4786c59 Prune slashing protection DB (#2194)
## Proposed Changes

Prune the slashing protection database so that it doesn't exhibit unbounded growth. Prune by dropping attestations and blocks from more than 512 epochs ago, relying on the guards that prevent signing messages with slots or epochs less than the minimum recorded in the DB.

The pruning process is potentially time consuming, so it's scheduled to run only every 512 epochs, in the last 2/3rds of a slot. This gives it at least 4 seconds to run without impacting other signing, which I think should be sufficient. I've seen it run for several minutes (yikes!) on our Pyrmont nodes, but I suspect that 1) this will only occur on the first run when the database is still huge 2) no other production users will be impacted because they don't have enough validators per node.

Pruning also happens at start-up, as I figured this is a fairly infrequent event, and if a user is experiencing problems with the VC related to pruning, it's nice to be able to trigger it with a quick restart. Users are also conditioned to not mind missing a few attestations during a restart.

We need to include a note in the release notes that users may see the message `timed out waiting for connection` the first time they prune a huge database, but that this is totally fine and to be expected (the VC will miss those attestations in the meantime).

I'm also open to making this opt-in for now, although the sooner we get users doing it, the less painful it will be: prune early, prune often!

a764c3b247 Handle early blocks (#2155)
## Issue Addressed

NA

## Problem this PR addresses

There's an issue where Lighthouse is banning a lot of peers due to the following sequence of events:

1. Gossip block 0xabc arrives ~200ms early
    - It is propagated across the network, with respect to [`MAXIMUM_GOSSIP_CLOCK_DISPARITY`](https://github.com/ethereum/eth2.0-specs/blob/v1.0.0/specs/phase0/p2p-interface.md#why-is-there-maximum_gossip_clock_disparity-when-validating-slot-ranges-of-messages-in-gossip-subnets).
    - However, it is not imported to our database since the block is early.
2. Attestations for 0xabc arrive, but the block was not imported.
    - The peer that sent the attestation is down-voted.
        - Each unknown-block attestation causes a score loss of 1, the peer is banned at -100.
        - When the peer is on an attestation subnet there can be hundreds of attestations, so the peer is banned quickly (before the missed block can be obtained via rpc).

## Potential solutions

I can think of three solutions to this:

1. Wait for attestation-queuing (#635) to arrive and solve this.
    - Easy
    - Not immediate fix.
    - Whilst this would work, I don't think it's a perfect solution for this particular issue, rather (3) is better.
1. Allow importing blocks with a tolerance of `MAXIMUM_GOSSIP_CLOCK_DISPARITY`.
    - Easy
    - ~~I have implemented this, for now.~~
1. If a block is verified for gossip propagation (i.e., signature verified) and it's within `MAXIMUM_GOSSIP_CLOCK_DISPARITY`, then queue it to be processed at the start of the appropriate slot.
    - More difficult
    - Feels like the best solution, I will try to implement this.
    
    
**This PR takes approach (3).**

- Implement the `block_delay_queue`, based upon a [`DelayQueue`](https://docs.rs/tokio-util/0.6.3/tokio_util/time/delay_queue/struct.DelayQueue.html) which can store blocks until it's time to import them.
- Add a new `DelayedImportBlock` variant to the `beacon_processor::WorkEvent` enum to handle this new event.
- In the `BeaconProcessor`, refactor a `tokio::select!` to a struct with an explicit `Stream` implementation. I experienced some issues with `tokio::select!` in the block delay queue and I also found it hard to debug. I think this explicit implementation is nicer and functionally equivalent (apart from the fact that `tokio::select!` randomly chooses futures to poll, whereas now we're deterministic).
- Add a testing framework to the `beacon_processor` module that tests this new block delay logic. I also tested a handful of other operations in the beacon processor (attns, slashings, exits) since it was super easy to copy-pasta the code from the `http_api` tester.
    - To implement these tests I added the concept of an optional `work_journal_tx` to the `BeaconProcessor` which will spit out a log of events. I used this in the tests to ensure that things were happening as I expect.
    - The tests are a little racey, but it's hard to avoid that when testing timing-based code. If we see CI failures I can revise. I haven't observed *any* failures due to races on my machine or on CI yet.
    - To assist with testing I allowed for directly setting the time on the `ManualSlotClock`.
- I gave the `beacon_processor::Worker` a `Toolbox` for two reasons; (a) it avoids changing tons of function sigs when you want to pass a new object to the worker and (b) it seemed cute.

399d073ab4 Fix lighthouse_version (#2221)
## Proposed Changes

Somehow since Lighthouse v1.1.3 the behaviour of `git-describe` has changed so that it includes the version tag, the number of commits since that tag, _and_ the commit. According to the docs this is how it should always have behaved?? Weird!

https://git-scm.com/docs/git-describe/2.30.1

Anyway, this lead to `lighthouse_version` producing this monstrosity of a version string when building #2194:

```
Lighthouse/v1.1.3-v1.1.3-5-gac07
```

Observe it in the wild here: https://pyrmont.beaconcha.in/block/694880

Adding `--exclude="*"` prevents `git-describe` from trying to include the tag, and on that troublesome commit from #2194 it now produces the correct version string.

8949ae7c4e Address ENR update loop (#2216)
## Issue Addressed

- Resolves #2215

## Proposed Changes

Addresses a potential loop when the majority of peers indicate that we are contactable via an IPv6 address.

See https://github.com/sigp/discv5/pull/62 for further rationale.

## Additional Info

The alternative to this PR is to use `--disable-enr-auto-update` and then manually supply an `--enr-address` and `--enr-upd-port`. However, that requires the user to know their IP addresses in order for discovery to work properly. This might not be practical/achievable for some users, hence this hotfix.

f8cc82f2b1 Switch back to warp with cors wildcard support (#2211)
## Issue Addressed

- Resolves #2204
- Resolves #2205

## Proposed Changes

Switches to my fork of `warp` which contains support for cors wildcards: https://github.com/paulhauner/warp/tree/cors-wildcard

I have a PR open on the `warp` repo but it hasn't had any interest from the maintainers as of yet: https://github.com/seanmonstar/warp/pull/726. I think running from a fork is the best we can do for now.

613382f304 Add slot offset computing to be downloaded slot (#2198)
The current implementation assumes the range offset of slots downloaded on a batch to equal zero. This conflicts with the condition to consider this chain as sync. For finalized sync, it results in one extra batch being downloaded which can't be processed.

88cc222204 Advance state to next slot after importing block (#2174)
## Issue Addressed

NA

## Proposed Changes

Add an optimization to perform `per_slot_processing` from the *leading-edge* of block processing to the *trailing-edge*. Ultimately, this allows us to import the block at slot `n` faster because we used the tail-end of slot `n - 1` to perform `per_slot_processing`.

Additionally, add a "block proposer cache" which allows us to cache the block proposer for some epoch. Since we're now doing trailing-edge `per_slot_processing`, we can prime this cache with the values for the next epoch before those blocks arrive (assuming those blocks don't have some weird forking).

There were several ancillary changes required to achieve this: 

- Remove the `state_root` field  of `BeaconSnapshot`, since there's no need to know it on a `pre_state` and in all other cases we can just read it from `block.state_root()`.
    - This caused some "dust" changes of `snapshot.beacon_state_root` to `snapshot.beacon_state_root()`, where the `BeaconSnapshot::beacon_state_root()` func just reads the state root from the block.
- Rename `types::ShuffingId` to `AttestationShufflingId`. I originally did this because I added a `ProposerShufflingId` struct which turned out to be not so useful. I thought this new name was more descriptive so I kept it.
- Address https://github.com/ethereum/eth2.0-specs/pull/2196
- Add a debug log when we get a block with an unknown parent. There was previously no logging around this case.
- Add a function to `BeaconState` to compute all proposers for an epoch without re-computing the active indices for each slot.

## Additional Info

- ~~Blocked on #2173~~
- ~~Blocked on #2179~~ That PR was wrapped into this PR.
- There's potentially some places where we could avoid computing the proposer indices in `per_block_processing` but I haven't done this here. These would be an optimization beyond the issue at hand (improving block propagation times) and I think this PR is already doing enough. We can come back for that later.

## TODO

- [x] Tidy, improve comments.
- [x] ~~Try avoid computing proposer index in `per_block_processing`?~~
