This is what it was likely causing PeerRemove tests to fail randomly
but very often. We cancelled the Cluster context before shutting down
the Consensus component. This killed networking and aborted
the peer remove operations when the leader is removing itself.
As a result, it would error with "leadership lost", which would
trigger a retry which would set the final error to "context cancelled"
because the shutdown of the consensus component proceeds during the
retry, cancelling the consensus context.
This is not only affecting tests, it might affected operations when
running cluster.
