// ** Releases **
// Released records are records which have been confirmed by the leader to have been at some point correctly replicated.
// Leader only confirms record with LogIdx X if all records up to and including X have been correctly replicated.
// This guarantee simplifies the message structure as we can move release point with a single message.
// Releases are not required from correctness perspective but they improve performance as we have a guarantee that any record
// before the release point can be read without having a quorum of replicas. It also allows followers to apply release records
// to a state machine wihout first checking if the record has been correctly replicated.
// It also simplifies cleanup during leader election. Imagine following scenario:
// Leader is replica 0, R indicates that a record is replicated to specific replica X that it's not
// Leader replication window
// ReplicaId LogIdx(2) LogIdx(3) LogIdx(4)
// 0 R R R
// 1 X R X
// 2 R X R
// 3 R X R
// 4 R X R
// Replicas (0,1) suddenly go away
// Replicas (2,3,4) elect 2 as new leader
// During "recovery" (a process which cleans up after previous leader from LastReleasedIdx)
// They don't see Record with LogIdx(3). Because they got a majority of nodes saying there is no record
// They know it couldn't have been correctly replicated. It is safe to drop it and all records after it.
// Because we don't want holes or conflicts we rewind logIndex to 3 and next appended record will come with 3
// What happens when replicas (0,1) come back. They will receive a movement of release point to arbitraty point in the future
// However they will, based on the leader token, notice it comes from a different leader.
// Since they were not part of the leader election they know their records after last released point have not been taken into
// account and could have been overwriten. They at this point drop these records and catch up from lastReleased point.
