Add a function for getting the lists of enabled/disabled mgr modules
from ceph. This is private for the moment as general module management
probably shouldn't be part of cephfs admin. It's bad enough we hacked
in the functions for enabling mirroring. :-)

Add functions EnableMirroringModule and DisableMirroringModule for
turning on an off the mirroring module at the ceph mgr.
This also adds the lower level EnableModule and DisableModule that take
a string parameter naming the module, and are the base for
EnableMirroringModule and DisableMirroringModule.
