Commit Message

NRG: Removed leader may reappear in membership (#7649)

When a leader is peer-removed it will send a EntryPeerRemove followed by
EntryLeaderTransfer. Normally a follower will commit EntryPeerRemove
after receiving processing EntryLeaderTranfer. However, if the leader
sneaks in a hearbeat in between, the heartbeat will commit the
EntryPeerRemove. When EntryPeerRemove is committed, then `n.peers` will
no longer contain the remove leader. However, when EntryLeaderTransfer
is processed, the follower would re-create an entry for the removed
leader in its `n.peers` set.
