 Specifically, when signing an `Attestation`, a validator should perform the following steps in the following order:
 1. Save a record to hard disk that an attestation has been signed for source -- `attestation_data.justified_slot // EPOCH_LENGTH` -- and target -- `attestation_data.slot // EPOCH_LENGTH`.
