## Proposed Changes
I did some gardening 🌳 in our dependency tree:
- Remove duplicate versions of `warp` (git vs patch)
- Remove duplicate versions of lots of small deps: `cpufeatures`, `ethabi`, `ethereum-types`, `bitvec`, `nix`, `libsecp256k1`.
- Update MDBX (should resolve#3028). I tested and Lighthouse compiles on Windows 11 now.
- Restore `psutil` back to upstream
- Make some progress updating everything to rand 0.8. There are a few crates stuck on 0.7.
Hopefully this puts us on a better footing for future `cargo audit` issues, and improves compile times slightly.
## Additional Info
Some crates are held back by issues with `zeroize`. libp2p-noise depends on [`chacha20poly1305`](https://crates.io/crates/chacha20poly1305) which depends on zeroize < v1.5, and we can only have one version of zeroize because it's post 1.0 (see https://github.com/rust-lang/cargo/issues/6584). The latest version of `zeroize` is v1.5.4, which is used by the new versions of many other crates (e.g. `num-bigint-dig`). Once a new version of chacha20poly1305 is released we can update libp2p-noise and upgrade everything to the latest `zeroize` version.
I've also opened a PR to `blst` related to zeroize: https://github.com/supranational/blst/pull/111
## Proposed Changes
Lots of lint updates related to `flat_map`, `unwrap_or_else` and string patterns. I did a little more creative refactoring in the op pool, but otherwise followed Clippy's suggestions.
## Additional Info
We need this PR to unblock CI.
## Issue Addressed
NA
## Proposed Changes
As `cargo audit` astutely pointed out, the version of `zeroize_derive` were were using had a vulnerability:
```
Crate: zeroize_derive
Version: 1.1.0
Title: `#[zeroize(drop)]` doesn't implement `Drop` for `enum`s
Date: 2021-09-24
ID: RUSTSEC-2021-0115
URL: https://rustsec.org/advisories/RUSTSEC-2021-0115
Solution: Upgrade to >=1.2.0
```
This PR updates `zeroize` and `zeroize_derive` to appease `cargo audit`.
`tiny-bip39` was also updated to allow compile.
## Additional Info
I don't believe this vulnerability actually affected the Lighthouse code-base directly. However, `tiny-bip39` may have been affected which may have resulted in some uncleaned memory in Lighthouse. Whilst this is not ideal, it's not a major issue. Zeroization is a nice-to-have since it only protects from sophisticated attacks or attackers that already have a high level of access already.
## 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

## Issue Addressed
`test_dht_persistence` failing
## Proposed Changes
Bind `NetworkService::start` to an underscore prefixed variable rather than `_`. `_` was causing it to be dropped immediately
This was failing 5/100 times before this update, but I haven't been able to get it to fail after updating it

## Proposed Changes
Cleans up some of my TODOs in the code base.
- Adds link to issue in this repo for BLST `unsafe` block.
- Confirms that the `nextaccount` field *is* required on an EIP-2386 wallet.
- Reference: https://github.com/mcdee/EIPs/blob/master/EIPS/eip-2386.md#json-schema
- Removes TODO about Zeroize on bip39 that was resolved in #1701
- Removes a TODO about an early randao reveal since we use the slot clock to generate the reveal: c4bd9c86e6/validator_client/src/block_service.rs (L212-L220)

## Proposed Changes
- Implements a HTTP API for the validator client.
- Creates EIP-2335 keystores with an empty `description` field, instead of a missing `description` field. Adds option to set name.
- Be more graceful with setups without any validators (yet)
- Remove an error log when there are no validators.
- Create the `validator` dir if it doesn't exist.
- Allow building a `ValidatorDir` without a withdrawal keystore (required for the API method where we only post a voting keystore).
- Add optional `description` field to `validator_definitions.yml`
## TODO
- [x] Signature header, as per https://github.com/sigp/lighthouse/issues/1269#issuecomment-649879855
- [x] Return validator descriptions
- [x] Return deposit data
- [x] Respect the mnemonic offset
- [x] Check that mnemonic can derive returned keys
- [x] Be strict about non-localhost
- [x] Allow graceful start without any validators (+ create validator dir)
- [x] Docs final pass
- [x] Swap to EIP-2335 description field.
- [x] Fix Zerioze TODO in VC api types.
- [x] Zeroize secp256k1 key
## Endpoints
- [x] `GET /lighthouse/version`
- [x] `GET /lighthouse/health`

## Proposed Changes
Add a `lighthouse am wallet recover` command that recreates a wallet from a mnemonic but no validator keys. Add a `lighthouse am validator recover` command which would directly create keys from a mnemonic for a given index and count.

## Issue Addressed
- Resolves#1361
## Proposed Changes
Loosens the constraints imposed by EIP-2335 so we can import keys from Prysm.

## 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
