MDSMonitor: cleanup and protect fsmap access

This commit is designed to permanently protect the current epoch FSMap from
accidental changes. Modifications to the pending_fsmap are protected by
checking if the monitor is the leader. Additionally, code must explicitly
request a writeable reference.

Fixes http://tracker.ceph.com/issues/23762
