Pawan Dhananjay 34d22b5920 Reduce validator monitor logging verbosity (#2606) 
## Issue Addressed

Resolves #2541

## Proposed Changes

Reduces verbosity of validator monitor per epoch logging by batching info logs for multiple validators.

Instead of a log for every validator managed by the validator monitor, we now batch logs for attestation records for previous epoch.

Before:
```log
Sep 20 06:53:08.239 INFO Previous epoch attestation success      validator: 1, epoch: 65875, matched_head: true, matched_target: true, inclusion_lag: 0 slot(s), service: val_mon

Sep 20 06:53:08.239 ERRO Previous epoch attestation missing      validator: 10, epoch: 65875, service: val_mon
```

after
```

```

The detailed individual logs are downgraded to debug logs.
