Ceph » mgr

Tried `ceph tell mgr enable_auth false` (enable_auth being implemented by the rest module). The ceph CLI became unresponsive (never returned to the shell). Meanwhile, mgr crashed with:

/home/tserong/src/github/SUSE/ceph/src/mgr/PyModules.cc: 546: FAILED assert(set_cmd.r == 0)

Why is the mon giving mgr "access denied" when it tries to set a config key?

We should consider getting rid of that assert too...
