Refactor: Remove redundant storage of last-quorum-acked-time in Leading.vote
Previously,
Leading.vote.utime()
held the last timestamp acknowledgedby a quorum, marking the beginning of the leader lease. The
Leading
struct updates and calculates this timestamp upon receiving an
AppendEntries
reply (includes heartbeat) from a follower.However, the leader's own timestamp was not being updated in this
process.
With this commit, we now update the leader's timestamp every time the
last-quorum-acked-time is accessed. This constant recalculation
makes storing the timestamp in
Leading.vote
unnecessary, hence it hasbeen removed to streamline the code.
