303deb9969 Rust 1.54.0 lints (#2483)
## Issue Addressed

N/A

## Proposed Changes

- Removing a bunch of unnecessary references
- Updated `Error::VariantError` to `Error::Variant`
- There were additional enum variant lints that I ignored, because I thought our variant names were fine
- removed `MonitoredValidator`'s `pubkey` field, because I couldn't find it used anywhere. It looks like we just use the string version of the pubkey (the `id` field) if there is no index

b4689e20c6 Altair consensus changes and refactors (#2279)
## Proposed Changes

Implement the consensus changes necessary for the upcoming Altair hard fork.

## Additional Info

This is quite a heavy refactor, with pivotal types like the `BeaconState` and `BeaconBlock` changing from structs to enums. This ripples through the whole codebase with field accesses changing to methods, e.g. `state.slot` => `state.slot()`.

3b901dc5ec Pack attestations into blocks in parallel (#2307)
## Proposed Changes

Use two instances of max cover when packing attestations into blocks: one for the previous epoch, and one for the current epoch. This reduces the amount of computation done by roughly half due to the `O(n^2)` running time of max cover (`2 * (n/2)^2 = n^2/2`). This should help alleviate some load on block proposal, particularly on Prater.

79fd9b32b9 Update pool/attestations and committees endpoints (#1899)
## Issue Addressed

Catching up on a few eth2 spec updates:

## Proposed Changes

- adding query params to the `GET pool/attestations` endpoint
- allowing the `POST pool/attestations` endpoint to accept an array of attestations
    - batching attestation submission
- moving `epoch` from a path param to a query param in the `committees` endpoint

103103e72e Address queue congestion in migrator (#1923)
## Issue Addressed

*Should* address #1917

## Proposed Changes

Stops the `BackgroupMigrator` rx channel from backing up with big `BeaconState` messages.

Looking at some logs from my Medalla node, we can see a discrepancy between the head finalized epoch and the migrator finalized epoch:

```
Nov 17 16:50:21.606 DEBG Head beacon block                       slot: 129214, root: 0xbc7a…0b99, finalized_epoch: 4033, finalized_root: 0xf930…6562, justified_epoch: 4035, justified_root: 0x206b…9321, service: beacon
Nov 17 16:50:21.626 DEBG Batch processed                         service: sync, processed_blocks: 43, last_block_slot: 129214, chain: 8274002112260436595, first_block_slot: 129153, batch_epoch: 4036
Nov 17 16:50:21.626 DEBG Chain advanced                          processing_target: 4036, new_start: 4036, previous_start: 4034, chain: 8274002112260436595, service: sync
Nov 17 16:50:22.162 DEBG Completed batch received                awaiting_batches: 5, blocks: 47, epoch: 4048, chain: 8274002112260436595, service: sync
Nov 17 16:50:22.162 DEBG Requesting batch                        start_slot: 129601, end_slot: 129664, downloaded: 0, processed: 0, state: Downloading(16Uiu2HAmG3C3t1McaseReECjAF694tjVVjkDoneZEbxNhWm1nZaT, 0 blocks, 1273), epoch: 4050, chain: 8274002112260436595, service: sync
Nov 17 16:50:22.654 DEBG Database compaction complete            service: beacon
Nov 17 16:50:22.655 INFO Starting database pruning               new_finalized_epoch: 2193, old_finalized_epoch: 2192, service: beacon
```

I believe this indicates that the migrator rx has a backed-up queue of `MigrationNotification` items which each contain a `BeaconState`.

## TODO

- [x] Remove finalized state requirement for op-pool

7f73dccebc Refine op pool pruning (#1805)
## Issue Addressed

Closes #1769
Closes #1708

## Proposed Changes

Tweaks the op pool pruning so that the attestation pool is pruned against the wall-clock epoch instead of the finalized state's epoch. This should reduce the unbounded growth that we've seen during periods without finality.

Also fixes up the voluntary exit pruning as raised in #1708.

8f86baa48d Optimize attester slashing (#1745)
## Issue Addressed

Closes #1548 

## Proposed Changes

Optimizes attester slashing choice by choosing the ones that cover the most amount of validators slashed, with the highest effective balances 

## Additional Info

Initial pass, need to write a test for it

Implement standard eth2.0 API (#1569)
- Resolves #1550
- Resolves #824
- Resolves #825
- Resolves #1131
- Resolves #1411
- Resolves #1256
- Resolve #1177

- Includes the `ShufflingId` struct initially defined in #1492. That PR is now closed and the changes are included here, with significant bug fixes.
- Implement the https://github.com/ethereum/eth2.0-APIs in a new `http_api` crate using `warp`. This replaces the `rest_api` crate.
- Add a new `common/eth2` crate which provides a wrapper around `reqwest`, providing the HTTP client that is used by the validator client and for testing. This replaces the `common/remote_beacon_node` crate.
- Create a `http_metrics` crate which is a dedicated server for Prometheus metrics (they are no longer served on the same port as the REST API). We now have flags for `--metrics`, `--metrics-address`, etc.
- Allow the `subnet_id` to be an optional parameter for `VerifiedUnaggregatedAttestation::verify`. This means it does not need to be provided unnecessarily by the validator client.
- Move `fn map_attestation_committee` in `mod beacon_chain::attestation_verification` to a new `fn with_committee_cache` on the `BeaconChain` so the same cache can be used for obtaining validator duties.
- Add some other helpers to `BeaconChain` to assist with common API duties (e.g., `block_root_at_slot`, `head_beacon_block_root`).
- Change the `NaiveAggregationPool` so it can index attestations by `hash_tree_root(attestation.data)`. This is a requirement of the API.
- Add functions to `BeaconChainHarness` to allow it to create slashings and exits.
- Allow for `eth1::Eth1NetworkId` to go to/from a `String`.
- Add functions to the `OperationPool` to allow getting all objects in the pool.
- Add function to `BeaconState` to check if a committee cache is initialized.
- Fix bug where `seconds_per_eth1_block` was not transferring over from `YamlConfig` to `ChainSpec`.
- Add the `deposit_contract_address` to `YamlConfig` and `ChainSpec`. We needed to be able to return it in an API response.
- Change some uses of serde `serialize_with` and `deserialize_with` to a single use of `with` (code quality).
- Impl `Display` and `FromStr` for several BLS fields.
- Check for clock discrepancy when VC polls BN for sync state (with +/- 1 slot tolerance). This is not intended to be comprehensive, it was just easy to do.

- See #1434 for a per-endpoint overview.
- Seeking clarity here: https://github.com/ethereum/eth2.0-APIs/issues/75

b73c497be2 Support multiple BLS implementations (#1335)
## Issue Addressed

NA

## Proposed Changes

- Refactor the `bls` crate to support multiple BLS "backends" (e.g., milagro, blst, etc).
- Removes some duplicate, unused code in `common/rest_types/src/validator.rs`.
- Removes the old "upgrade legacy keypairs" functionality (these were unencrypted keys that haven't been supported for a few testnets, no one should be using them anymore).

## Additional Info

Most of the files changed are just inconsequential changes to function names.

## TODO

- [x] Optimization levels
- [x] Infinity point: https://github.com/supranational/blst/issues/11
- [x] Ensure milagro *and* blst are tested via CI
- [x] What to do with unsafe code?
- [x] Test infinity point in signature sets
