Description

'last_known_addr' field is not persisted for a single master Raft
configuration. This is okay as long as we have a single master
configuration. On dynamically transitioning from single master
to two master configuration, ChangeConfig() request to ADD_PEER
fails the validation in VerifyRaftConfig().
