This was occasionally useful for establishing a journal-less
performance baseline, but it has two big problems:
* We don't test it, so it's probably broken a lot of the time
* It sounds a lot to a naive user like an option for controlling
logging.
IMO, anyone who wants this behaviour is in sufficiently advanced
territory that then can hack it in and recompile, we don't need
to leave dangerous things like this in our releases.

It is now required that all changes to max_mds use the run-time `ceph fs
set max_mds` command. The rationale for this change is that it is
confusing to have a configuration for max_mds which is only observed at
file system creation.
