- Create trait `ValidatorStore` with all functions used by the `validator_services`
- Make `validator_services` generic on `S: ValidatorStore`
- Introduce `LighthouseValidatorStore`, which has identical functionality to the old `ValidatorStore`
- Remove dependencies (especially `environment`) from `validator_services` and `beacon_node_fallback` in order to be able to cleanly use them in Anchor
Cleaned up and isolated version of the `--disable-attesting` flag for the VC, from the `holesky-rescue` branch:
- https://github.com/sigp/lighthouse/pull/7041
I figured we don't need the `--disable-attesting` flag on the BN for now, and it was a much more invasive impl.

2 changes:
1. Replace Option::map_or(true, ...) with is_none_or(...)
2. Remove unnecessary `Into::into` blocks where the type conversion is apparent from the types
