f26adc0a36 Lighthouse v0.2.0 (Medalla) (#1452)
## Issue Addressed

NA

## Proposed Changes

- Moves the git-based versioning we were doing into the `lighthouse_version` crate in `common`.
- Removes the `beacon_node/version` crate, replacing it with `lighthouse_version`.
- Bumps the version to `v0.2.0`.

## Additional Info

There are now two types of version string:

1. `const VERSION: &str = Lighthouse/v0.2.0-1419501f2+`
1. `version_with_platform() = Lighthouse/v0.2.0-1419501f2+/x86_64-linux`

(1) is handy cause it's a `const` and shorter. (2) has platform info so it's more useful. Note that the plus-sign (`+`) indicates the the git commit is dirty (it used to be `(modified)` but I had to shorten it to fit into graffiti).

These version strings are now included on:

- `lighthouse --version`
- `lcli --version`
- `curl localhost:5052/node/version`
- p2p messages when we communicate our version

You can update the version by changing this constant (version is not related to a `Cargo.toml`):

f634f073a8 Correct issue with network message passing (#1439)
## Issue Addressed

Sync was breaking occasionally. The root cause appears to be identify crashing as events we being sent to the protocol after nodes were banned. Have not been able to reproduce sync issues since this update. 

## Proposed Changes

Only send messages to sub-behaviour protocols if the peer manager thinks the peer is connected. All other messages are dropped.

3b5da8f35f Gossipsub update (#1432)
## Issue Addressed

The most recent gossipsub update had an issue where some privacy settings lead to not sending a sequence number with the message. Although Lighthouse treats these as valid (based on current configuration) other clients may not. 

This corrects gossipsub to send sequence numbers where expected and based on the configuration settings.

3ea01ac26b Add top-level feature to enable Milagro (#1428)
## Proposed Changes

In the continuing war against unportable binaries I figured we should have an option to enable building the Lighthouse binary itself with Milagro. This PR adds a `milagro` feature that can be used with `cargo install --path lighthouse --features milagro --force --locked`. The BLS library in-use will also show up under `lighthouse --version` like this:

```
Lighthouse 0.1.2-7d8acc20a(modified)
BLS Library: milagro
```

Future work: add other cool stuff like the compiler version and CPU target to `--version`.

d0f1a3e59f Check deposit signatures when submitting via CLI (#1414)
## Proposed Changes

Having been bitten by submitting deposits with invalid signatures (for the wrong testnet), I'm proposing we check the signatures of deposits when submitting them via `lighthouse account validator deposit`.

The impact on performance is likely to be minimal because waiting for an Eth1 transaction confirmation takes a lot longer than verifying a single signature.

It would be great to have the same protection in the deposit web UI in the Lighthouse Book, but I imagine that will be obsoleted by the validator web UI work.

4d77784bb8 Rate limit RPC requests (#1402)
## Issue Addressed
#1056 

## Proposed Changes
- Add a rate limiter to the RPC behaviour. This also means the rate limiting occurs just before the door to the application level, so the number of connections a peer opens does not affect this (this would happen in the future if put on the handler)
- The algorithm used is the leaky bucket as a meter / token bucket implemented the GCRA way
- Each protocol has its own limit. Due to the way the algorithm works, the "small" protocols have a hard limit, while bbrange and bbroot allow [burstiness](https://www.wikiwand.com/en/Burstiness). This is so that a peer can't request hundreds of individual requests expecting only one block in a short period of time, it also allows a peer to send two half size requests instead of one with max if they want to without getting limited, and.. it also allows a peer to request a batch of the maximum size and then send _appropriately spaced_ requests of really small sizes. From what I've seen in sync this is plausible when reaching the target slot.

Needs to be heavily tested

7d8acc20a0 Add a flag to make lighthouse portable across machines (#1423)
## Issue Addressed

Closes #1395

## Proposed Changes

* Add a feature to `lighthouse` and `lcli` called `portable` which enables the `portable` feature on our fork of BLST. This feature turns off the `-march=native` C compiler flag that produces binaries highly targeted to the host CPU's instruction set.
* Tweak the `Makefile` so that when the `PORTABLE` environment variable is set to `true`, it compiles with this feature.
* Temporarily enable `PORTABLE=true` in the Docker build so that the image on Docker Hub is portable. Eventually I think we should enable `PORTABLE=true` _only on Docker Hub_, so that users building locally can take advantage of the tasty compiler magic. This seems to be possible by setting a Docker Hub environment variable: https://docs.docker.com/docker-hub/builds/#environment-variables-for-builds

## Additional Info

Tested by compiling on a very new CPU (Intel Core i7-8550U) and copying the binary to a very old CPU (Intel Core i3 530). Before the portability fix, this produced the SIGILL crash described in #1395, and after the fix, it worked smoothly.

I'm in the process of testing the Docker build and running some benches to confirm that the performance penalty isn't too severe.

395d99ce03 Sync update (#1412)
## Issue Addressed

Recurring sync loop and invalid batch downloading

## Proposed Changes

Shifts the batches to include the first slot of each epoch. This ensures the finalized is always downloaded once a chain has completed syncing. 

Also add in logic to prevent re-dialing disconnected peers. Non-performant peers get disconnected during sync, this prevents re-connection to these during sync.

9ae9df806c Fix clippy lints rpc (#1401)
## Issue Addressed
#1388 partially (eth2_libp2p & network)

## Proposed Changes 
TLDR at the end
- *Complex types* are 3 on the handlers/Behaviours but the types are `Poll<ComplexType>` where `ComplexType` comes from the traits of libp2p. Those, I don't thing are worth an alias. A couple more were from using tokio combinators and were removed writing things the async way and using [`BoxFuture`](https://docs.rs/futures/0.3.5/futures/future/type.BoxFuture.html)
- The *cognitive complexity*.. I tried to address those before (they come from the poll functions too) and tbh they are cognitively simpler to understand the way they are now. Moving separate parts to functions doesn't add much since that code is not repeated and they all do early returns. If moved those returns would now need to be wrapped in an Option, probably, and checked to be returned again. I would leave them like that but that's just preference.
- *Too many arguments*: They are not easily put together in a wrapping struct since the parameters don't relate semantically (Ex: fn new with a log, a reference to the chain, a peer, etc) but some may differ.
- *Needless returns* were indeed needless

## Additional Info
TLDR: removed needless return, used BoxFuture and async, left the rest untouched since those lgtm

21bcc8848d Add caching for state.eth1_data_votes (#919)
## Issue Addressed

NA

## Proposed Changes

Adds additional tree hash caching for `state.eth1_data_votes`.

Presently, each time we tree hash the `BeaconState`, we recompute the `state.eth1_data_votes` tree in it's entirety. This is because we only previous had support for caching fixed-length lists.

This PR adds the `Eth1DataVotesTreeHashCache` which provides caching for the `state.eth1_data_votes` list. The cache is aware of `SLOTS_PER_ETH1_VOTING_PERIOD` and will reset itself whenever that boundary is crossed.

This cache adds a new (but somewhat fundamental) restriction to tree hash caching:

*For some state `s`, `s.tree_hash_cache` is only valid for `s` or descendants of `s` that have been reached via state transitions that are faithful to the specification (invalid blocks are permitted, as long as they are faithfully processed).*

ba10c80633 Refactor inbound substream logic with async (#1325)
## Issue Addressed
#1112 

The logic is slightly different but still valid wrt to error handling.
- Inbound state is either Busy with a future that return the subtream (and info about the processing)
- The state machine works as follows:
  - `Idle` with pending responses => `Busy`
  - `Busy` => finished ? if so and there are new pending responses then `Busy`, if not then `Idle`
               => not finished remains `Busy`
- Add an `InboundInfo` for readability
- Other stuff:
  - Close inbound substreams when all expected responses are sent
  - Remove the error variants from `RPCCodedResponse` and use the codes instead
  - Fix various spelling mistakes because I got sloppy last time

3a888d6ef3 Fix early return from DepositLog parsing (#1382)
## Issue Addressed

N/A

## Proposed Changes

When parsing deposit logs, we were returning an error in case `PublicKeyBytes` or `SignatureBytes` didn't convert to valid bls `PublicKey` or `Signature` types. This would stall our import of deposit logs. 
Fixes this by returning `signature_is_valid` as `false` in `DepositLog` if the bytes are invalid `PublicKey/Signature` types.

Tested this fix on the Onyx deposit contract where the bug was observed and it works correctly as expected.

e26da35cbf Introduce validator definition file for VC (#1357)
## Issue Addressed

NA

## Proposed Changes

- Introduces the `valdiator_definitions.yml` file which serves as an explicit list of validators that should be run by the validator client.
  - Removes `--strict` flag, split into `--strict-lockfiles` and `--disable-auto-discover`  
  - Adds a "Validator Management" page to the book.
- Adds the `common/account_utils` crate which contains some logic that was starting to duplicate across the codebase.

The new docs for this feature are the best description of it (apart from the code, I guess): 9cb87e93ce/book/src/validator-management.md

## API Changes

This change should be transparent for *most* existing users. If the `valdiator_definitions.yml` doesn't exist then it will be automatically generated using a method that will detect all the validators in their `validators_dir`.

Users will have issues if they are:

1. Using `--strict`.
1. Have keystores in their `~/.lighthouse/validators` directory that weren't being detected by the current keystore discovery method.

For users with (1), the VC will refuse to start because the `--strict` flag has been removed. They will be forced to review `--help` and choose an equivalent flag.

For users with (2), this seems fairly unlikely and since we're only in testnets there's no *real* value on the line here. I'm happy to take the risk, it would be a different case for mainnet.

## Additional Info

This PR adds functionality we will need for #1347.

393782f632 Prefer viable nightly Rust builds for CI (#1379)
## Proposed Changes

CI is failing on PRs because of a regression in nightly Rust. This change forces `rustup` to install a version of the nightly compiler that can at least build `rustfmt`, which should reduce the frequency of this happening.

Alternatively, we could allow CI to succeed even when `cargo-udeps` fails, but I think we should avoid doing that unless we really have to.
