build: split ceph_ver.h

Split ceph_ver.h into:
1) ceph_ver.h containing git-related macros
2) ceph_release.h containing just human written ceph version number /
   ceph version name.

The benefit is that denc.h which needs to know CEPH_RELEASE value
can skip including git-related macros. There are many compilation units
that use denc.h and only few that need git-related macros.
Reduces amount of files to recompile after SHA1 changes.
It is only relevant for developer environment.

cephfs_mirror: Add ErrorListener to maintain blocklisted/failed timestamp in FSMirror

Have FSMirror register a listener with InstanceWatcher/MirrorWatcher which would get invoked when the mirror daemon is blocklisted or failed.
Thus FSMirror can maintain the last blocklisted/failed timestamp and use that for restarting the mirror daemon.
