protected void prePeerModification(MasterProcedureEnv env) throws IOException
ModifyPeerProcedureIf an IOException is thrown then we will give up and mark the procedure as failed directly. If all checks passes then the procedure can not be rolled back any more.

ModifyPeerProcedure
Notice that, since we have already done the actual work, throwing IOException here will
not fail this procedure, we will just ignore it and finish the procedure as suceeded. If
ReplicationException is thrown we will retry since this usually means we fails to
update the peer storage.
