## 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.
## Issue Addressed
This PR makes the `Eth1Chain::use_dummy_backend` field private. I believe this could be good to ensure the consistency of a Eth1Chain instance. 💡

## 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.
## TODO
- [x] Reconsider flags
- [x] Move doc into a more reasonable chapter.
- [x] Check for compile warnings.
## 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.
## Additional Info
Example failing run: https://github.com/sigp/lighthouse/runs/896694659
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.
## Issue Addressed
Prevent CI from succeeding when there are warnings. Code can still be built and tested with warnings locally, but CI may fail during a Rust update (which is fine IMO).
## Proposed Changes
* Deny warnings for all stable compiler jobs on CI (excludes `cargo udeps`, which runs under nightly)
* Fix the warnings currently on `master` related to unnecessary `mem::replace`
## Issue Addressed

## Proposed Changes
Add a command line option (`--http-allow-origin`) and a config item for configuring the `Access-Control-Allow-Origin` response header. This should unblock making XMLHttpRequests.
Downgrades libp2p and the gossipsub updates.
This looks to resolve the CPU usage issue we have been seeing.
The root cause is likely inside the latest gossipsub updates, which will be addressed in a later PR
## Issue Addressed
Closes#1319
## Proposed Changes
This issue:
1. Allows users to edit their Graffiti via the cli option `--graffiti`. If the graffiti is too long, lighthouse will not start and throw an error message. Otherwise, it will set the Graffiti to be the one provided by the user, right-padded with 0s.
2. Create a new `Graffiti` type and unify the code around it. With this type, everything is enforced at compile-time, and the code can be (I think...) panic-free! :)
## Additional info
Currently, only `&str` are supported, as this is the returned type by `.arg("graffiti")`.
Since this is user-input, I tried being as careful as I could. This is also why I created the `Graffiti` type, to make sure I could check as much as possible at compile time.

## Proposed Changes
Exits *earlier* when system is 32-bit. Previously we were trying (and failing) to parse the genesis SSZ first. This made for a bad user experience.
## Additional Info
NA
* Add latest commit info to git version
* Testing docker build
* Use fallback; modify format
* Revert "Testing docker build"
This reverts commit 197140d6973e22a6b891ebc0f1798d60c87b182a.
* Modify fallback to have crate version
