## Issue Addressed
Make sure gas limit examples in our docs represent sane values.
Thanks @dankrad for raising this in discord.
## Additional Info
We could also consider logging warnings about whether the gas limits configured are sane. Prysm has an open issue for this: https://github.com/prysmaticlabs/prysm/issues/10810

## Issue Addressed
Related: #3550
Remove references to the `--strict-fee-recipient` flag in docs. The flag will cause missed proposals prior to the merge transition.

## Issue Addressed
Resolves https://github.com/sigp/lighthouse/issues/3517
## Proposed Changes
Adds a `--builder-profit-threshold <wei value>` flag to the BN. If an external payload's value field is less than this value, the local payload will be used. The value of the local payload will not be checked (it can't really be checked until the engine API is updated to support this).

## Issue Addressed
https://github.com/sigp/lighthouse/issues/3091
Extends https://github.com/sigp/lighthouse/pull/3062, adding pre-bellatrix block support on blinded endpoints and allowing the normal proposal flow (local payload construction) on blinded endpoints. This resulted in better fallback logic because the VC will not have to switch endpoints on failure in the BN <> Builder API, the BN can just fallback immediately and without repeating block processing that it shouldn't need to. We can also keep VC fallback from the VC<>BN API's blinded endpoint to full endpoint.
## Proposed Changes
- Pre-bellatrix blocks on blinded endpoints
- Add a new `PayloadCache` to the execution layer
- Better fallback-from-builder logic
## Todos
- [x] Remove VC transition logic
- [x] Add logic to only enable builder flow after Merge transition finalization
- [x] Tests
- [x] Fix metrics
- [x] Rustdocs
