Description

Tombstoned replicas must reject remote bootstrap requests from rogue leaders, but the way they currently do this is too strict. Because a replica can independently rev its term, then be tombstoned, we need to stop comparing the consensus metadata term, but instead compare the term of the last opid in the log.
