> We might need to abort operations/transactions in certain cases. For instance when a leader gets disconnected from a majority of the quorum, and a new leader is elected, its non-majority replicated operations must be aborted. Similarly a replica that received a minority replicated operation from a leader might see that operation nullified by a subsequent leader.
> Aborting operations means:
> - cancelling ongoing transaction on all peers
> - have operation status trackers return a status on Wait()
> I started on this a while ago but this fell through the cracks as it was low pri then.
