tools/ceph-monstore-tools: add rewrite command

"rewrite" command will
 - add a new osdmap version to update current osdmap held by OSDMonitor
 - add a new paxos version, as a proposal it will
   * rewrite all osdmap epochs from specified epoch to  the last_committed
     one with the specified crush map.
   * add the new osdmap which is added just now
so the leader monitor can trigger a recovery process to apply the transaction
to all monitors in quorum, and hence bring them back to normal after being
injected with a faulty crushmap.
