Update lighthouse to version `v1.0.2`.
There are two major updates in this version:
- Updates to the task executor to tokio 0.3 and all sub-dependencies relying on core execution, including libp2p
- Update BLST
## Issue Addressed
Move to latest official version of blst (v0.3.1). Incorporate all the subgroup check API changes.
## Proposed Changes
Update Cargo.toml to use official blst crate 0.3.1
Modifications to blst.rs wrapper for subgroup check API changes
## Additional Info
The overall subgroup check methodology is public keys should be check for validity using key_validate() at time of first seeing them. This will check for infinity and in group. Those keys can then be cached for future usage. All calls into blst set the pk_validate boolean to false to indicate there is no need for on the fly checking of public keys in the library. Additionally the public keys are supposed to be validated for proof of possession outside of blst.
For signatures the subgroup check can be done at time of deserialization, prior to being used in aggregation or verification, or in the blst aggregation or verification functions themselves. In the interface wrapper the call to subgroup_check has been left for one instance, although that could be moved into the
verify_multiple_aggregate_signatures() call if wanted. Checking beforehand does save some compute resources in the scenario a bad signature is received. Elsewhere the subgroup check is being done inside the higher level operations. See comments in the code.
All checks on signature are done for subgroup only. There are no checks for infinity. The rationale is an aggregate signature could technically equal infinity. If any individual signature was infinity (invalid) then it would fail at time of verification. A loss of compute resources, although safety would be preserved.
## Description
This PR updates Lighthouse to tokio 0.3. It includes a number of dependency updates and some structural changes as to how we create and spawn tasks.
This also brings with it a number of various improvements:
- Discv5 update
- Libp2p update
- Fix for recompilation issues
- Improved UPnP port mapping handling
- Futures dependency update
- Log downgrade to traces for rejecting peers when we've reached our max

## Issue Addressed
part of #1883
## Proposed Changes
Adds a new cli argument `--eth1-endpoints` that can be used instead of `--eth1-endpoint` to specify a comma-separated list of endpoints. If the first endpoint returns an error for some request the other endpoints are tried in the given order.
## Additional Info
Currently if the first endpoint fails the fallbacks are used silently (except for `try_fallback_test_endpoint` that is used in `do_update` which logs a `WARN` for each endpoint that is not reachable). A question is if we should add more logs so that the user gets warned if his main endpoint is for example just slow and sometimes hits timeouts.
## Issue Addressed
Closes#1823
## Proposed Changes
* Use OS-level file locking for validator keystores, eliminating problems with lockfiles lingering after ungraceful shutdowns (`SIGKILL`, power outage). I'm using the `fs2` crate because it's cross-platform (unlike `file-lock`), and it seems to have the most downloads on crates.io.
* Deprecate + disable `--delete-lockfiles` CLI param, it's no longer necessary
* Delete the `validator_dir::Manager`, as it was mostly dead code and was only used in the `validator list` command, which has been rewritten to read the validator definitions YAML instead.
## Additional Info
Tested on:
- [x] Linux
- [x] macOS

## Issue Addressed
NA
## Proposed Changes
- Adds a HTTP server to the VC which provides Prometheus metrics.
- Moves the health metrics into the `lighthouse_metrics` crate so it can be shared between BN/VC.
- Sprinkle some metrics around the VC.
- Update the book to indicate that we now have VC metrics.
- Shifts the "waiting for genesis" logic later in the `ProductionValidatorClient::new_from_cli`
- This is worth attention during the review.
## Additional Info
- ~~`clippy` has some new lints that are failing. I'll deal with that in another PR.~~
This is an implementation of a slasher that lives inside the BN and can be enabled via `lighthouse bn --slasher`.
Features included in this PR:
- [x] Detection of attester slashing conditions (double votes, surrounds existing, surrounded by existing)
- [x] Integration into Lighthouse's attestation verification flow
- [x] Detection of proposer slashing conditions
- [x] Extraction of attestations from blocks as they are verified
- [x] Compression of chunks
- [x] Configurable history length
- [x] Pruning of old attestations and blocks
- [x] More tests
Future work:
* Focus on a slice of history separate from the most recent N epochs (e.g. epochs `current - K` to `current - M`)
* Run out-of-process
* Ingest attestations from the chain without a resync

## Issue Addressed
NA
## Proposed Changes
Removes most of the temporary string initializations in network metrics and replaces them by directly using `&str`. This further improves on PR https://github.com/sigp/lighthouse/pull/1895.
For the subnet id handling the current approach uses a build script to create a static map. This has the disadvantage that the build script hardcodes the number of subnets. If we want to use more than 64 subnets we need to adjust this in the build script.
## Additional Info
We still have some string initializations for the enum `PeerKind`. To also replace that by `&str` I created a PR in the libp2p dependency: https://github.com/sigp/rust-libp2p/pull/91. Either we wait with merging until this dependency PR is merged (and all conflicts with the newest libp2p version are resolved) or we just merge as is and I will create another PR when the dependency is ready.
## Issue Addressed
#1606
## Proposed Changes
Uses dynamic gossipsub scoring parameters depending on the number of active validators as specified in https://gist.github.com/blacktemplar/5c1862cb3f0e32a1a7fb0b25e79e6e2c.
## Additional Info
Although the parameters got tested on Medalla, extensive testing using simulations on larger networks is still to be done and we expect that we need to change the parameters, although this might only affect constants within the dynamic parameter framework.
## Issue Addressed
Resolves#1704
## Proposed Changes
Update tiny-bip39 from using the sigp fork to the newly released v0.8.0 in the upstream.

The remote signer relies on the `types` and `crypto/bls` crates from Lighthouse. Moreover, a number of tests of the remote signer consumption of LH leverages this very signer, making any important update a potential dependency nightmare.

Updates libp2p to the latest version.
This adds tokio 0.3 support and brings back yamux support.
This also updates some discv5 configuration parameters for leaner discovery queries
## Issue Addressed
- Related to #1691
## Proposed Changes
Adds the following API endpoints:
- `GET lighthouse/eth1/syncing`: status about how synced we are with Eth1.
- `GET lighthouse/eth1/block_cache`: all locally cached eth1 blocks.
- `GET lighthouse/eth1/deposit_cache`: all locally cached eth1 deposits.
Additionally:
- Moves some types from the `beacon_node/eth1` to the `common/eth2` crate, so they can be used in the API without duplication.
- Allow `update_deposit_cache` and `update_block_cache` to take an optional head block number to avoid duplicate requests.
## Additional Info
TBC

## Proposed Changes
- Add quoted serde utils for `FixedVector` and `VariableList`
- Had to remove the dependency that `ssz_types` has on `serde_utils` to avoid a circular dependency.

## Issue Addressed
Resolve#1652
## Proposed Changes
Adds a cli option for voluntary exits. The flow is similar to prysm's where after entering the password for the validator keystore (or load password from `secrets` if present) the user is given multiple warnings about the operation being irreversible, then redirected to the docs webpage(not added yet) which explains what a voluntary exit is and the consequences of exiting and then prompted to enter a phrase from the docs webpage as a final confirmation.
Example usage
```
$ lighthouse --testnet zinken account validator exit --validator <validator-pubkey> --beacon-node http://localhost:5052
Running account manager for zinken testnet
validator-dir path: "..."
Enter the keystore password: for validator in ...
Password is correct
Publishing a voluntary exit for validator: ...
WARNING: This is an irreversible operation
WARNING: Withdrawing staked eth will not be possible until Eth1/Eth2 merge Please visit [website] to make sure you understand the implications of a voluntary exit.
Enter the phrase from the above URL to confirm the voluntary exit:
Exit my validator
Published voluntary exit for validator ...
```
## Additional info
Not sure if we should have batch exits (`--validator all`) option for exiting all the validators in the `validators` directory. I'm slightly leaning towards having only single exits but don't have a strong preference.
## Issue Addressed
Closes#1504Closes#1505
Replaces #1703Closes#1707
## Proposed Changes
* Update BLST and Milagro to versions compatible with BLSv4 spec
* Update Lighthouse to spec v1.0.0-rc.0, and update EF test vectors
* Use the v1.0.0 constants for `MainnetEthSpec`.
* Rename `InteropEthSpec` -> `V012LegacyEthSpec`
* Change all constants to suit the mainnet `v0.12.3` specification (i.e., Medalla).
* Deprecate the `--spec` flag for the `lighthouse` binary
* This value is now obtained from the `config_name` field of the `YamlConfig`.
* Built in testnet YAML files have been updated.
* Ignore the `--spec` value, if supplied, log a warning that it will be deprecated
* `lcli` still has the spec flag, that's fine because it's dev tooling.
* Remove the `E: EthSpec` from `YamlConfig`
* This means we need to deser the genesis `BeaconState` on-demand, but this is fine.
* Swap the old "minimal", "mainnet" strings over to the new `EthSpecId` enum.
* Always require a `CONFIG_NAME` field in `YamlConfig` (it used to have a default).
## Additional Info
Lots of breaking changes, do not merge! ~~We will likely need a Lighthouse v0.4.0 branch, and possibly a long-term v0.3.0 branch to keep Medalla alive~~.

As @AgeManning mentioned the newest libp2p version had some problems and got downgraded again on lighthouse master. This is an intermediate version that makes no problems and only adds a small change of allowing only one topic per message.
## Description
This downgrades the recent libp2p upgrade.
There were issues with the RPC which prevented syncing of the chain and this upgrade needs to be further investigated.
## Overview
This updates lighthouse to discovery v5.1
Note: This makes lighthouse's discovery not compatible with any previous version. Lighthouse cannot discover peers or send/receive ENR's from any previous version. This is a breaking change.
This resolves#1605
## Description
Updates to the latest libp2p and includes gossipsub updates.
Of particular note is the limitation of a single topic per gossipsub message.

## Issue Addressed
- Resolves#1727
## Proposed Changes
Remove the `lighthouse account validator deposit` command.
It's a shame to let this go, but it's currently lacking any tests and contains significant, un-handled edge-cases (e.g., it will wait forever until the eth1 node gives a tx confirmation and if you ctrl+c it before it finishes it will leave the filesystem in an unknown state with lockfiles lying around)
I don't think we need to make deposit functionality a priority before mainnet, we have bigger fish to fry IMO.
We, will need to revive this functionality before the next testnet, but I think we should make private, non-production tools to handle this for SigP internally.
## Additional Info
Be sure to re-open #1331 if this PR is abandoned.
## Issue Addressed
NA
## Proposed Changes
Adds a `lighthouse/beacon/states/:state_id/ssz` endpoint to allow us to pull the genesis state from the API.
## Additional Info
NA
## Issue Addressed
- Resolves#1766
## Proposed Changes
- Use the `warp::filters::cors` filter instead of our work-around.
## Additional Info
It's not trivial to enable/disable `cors` using `warp`, since using `routes.with(cors)` changes the type of `routes`. This makes it difficult to apply/not apply cors at runtime. My solution has been to *always* use the `warp::filters::cors` wrapper but when cors should be disabled, just pass the HTTP server listen address as the only permissible origin.
## Issue Addressed
`node` endpoints in #1434
## Proposed Changes
Implement these:
```
/eth/v1/node/health
/eth/v1/node/peers/{peer_id}
/eth/v1/node/peers
```
- Add an `Option<Enr>` to `PeerInfo`
- Finish implementation of `/eth/v1/node/identity`
## Additional Info
- should update the `peers` endpoints when #1764 is resolved

## Issue Addressed
Closes#1557
## Proposed Changes
Modify the pruning algorithm so that it mutates the head-tracker _before_ committing the database transaction to disk, and _only if_ all the heads to be removed are still present in the head-tracker (i.e. no concurrent mutations).
In the process of writing and testing this I also had to make a few other changes:
* Use internal mutability for all `BeaconChainHarness` functions (namely the RNG and the graffiti), in order to enable parallel calls (see testing section below).
* Disable logging in harness tests unless the `test_logger` feature is turned on
And chose to make some clean-ups:
* Delete the `NullMigrator`
* Remove type-based configuration for the migrator in favour of runtime config (simpler, less duplicated code)
* Use the non-blocking migrator unless the blocking migrator is required. In the store tests we need the blocking migrator because some tests make asserts about the state of the DB after the migration has run.
* Rename `validators_keypairs` -> `validator_keypairs` in the `BeaconChainHarness`
## Testing
To confirm that the fix worked, I wrote a test using [Hiatus](https://crates.io/crates/hiatus), which can be found here:
https://github.com/michaelsproul/lighthouse/tree/hiatus-issue-1557
That test can't be merged because it inserts random breakpoints everywhere, but if you check out that branch you can run the test with:
```
$ cd beacon_node/beacon_chain
$ cargo test --release --test parallel_tests --features test_logger
```
It should pass, and the log output should show:
```
WARN Pruning deferred because of a concurrent mutation, message: this is expected only very rarely!
```
## Additional Info
This is a backwards-compatible change with no impact on consensus.
## Proposed Changes
Adds a gossipsub topic filter that only allows subscribing and incoming subscriptions from valid ETH2 topics.
## Additional Info
Currently the preparation of the valid topic hashes uses only the current fork id but in the future it must also use all possible future fork ids for planned forks. This has to get added when hard coded forks get implemented.
DO NOT MERGE: We first need to merge the libp2p changes (see https://github.com/sigp/rust-libp2p/pull/70) so that we can refer from here to a commit hash inside the lighthouse branch.
## Proposed Changes
Implement the new message id function (see https://github.com/ethereum/eth2.0-specs/pull/2089) using an additional fast message id function for better performance + caching decompressed data.
## Issue Addressed
Resolves#1744
## Proposed Changes
- Add `directory::ensure_dir_exists` to the `ValidatorDefinition::open_or_create` method
- As @pawanjay176 suggested, making the `--validator-dir` non-global so users are forced to include the flag after the `validator` subcommand. Current behavior seems to be ignoring the flag if it comes after something like `validator import`
## Additional Info
N/A
## Issue Addressed
#1618
## Proposed Changes
Adds an encrypted key cache that is loaded on validator_client startup. It stores the keypairs for all enabled keystores and uses as password the concatenation the passwords of all enabled keystores. This reduces the number of time intensive key derivitions for `N` validators from `N` to `1`. On changes the cache gets updated asynchronously to avoid blocking the main thread.
## Additional Info
If the cache contains the keypair of a keystore that is not in the validator_definitions.yml file during loading the cache cannot get decrypted. In this case all the keystores get decrypted and then the cache gets overwritten. To avoid that one can disable keystores in validator_definitions.yml and restart the client which will remove them from the cache, after that one can entirely remove the keystore (from the validator_definitions.yml and from the disk).
Other solutions to the above "problem" might be:
* Add a CLI and/or API function for removing keystores which will update the cache (asynchronously).
* Add a CLI and/or API function that just updates the cache (asynchronously) after a modification of the `validator_definitions.yml` file.
Note that the cache file has a lock file which gets removed immediatly after the cache was used or updated.
## Issue Addressed
- Resolves#1706
