As dirfrags are now standard in CephFS, remove the machinery for
tracking and enabling this feature.
ceph fs set <fs> allow_dirfrags is now deprecated and prints a warning
message.

This reverts commit 3189ba19a7, reversing
changes made to b7620de020.
Despite the change in json format being positive, the unfortunate side-effect
is that it broke upgrade testing (because the QA framework must handle the
transition of mdsmap["info"] to a list from object) and the ceph-mgr.

These configs were used for initialization but it is more appropriate to
require setting these file system attributes via `ceph fs set`. This is similar
to what was already done with max_mds. There are new variables added for `fs

Right now, we have two different timeout settings -- one for when the
client is just not responding at all (mds_session_timeout), and one for
when the client is otherwise responding but isn't returning caps in a
timely fashion (mds_cap_revoke_timeout).
The default settings on them are equivalent (60s), but only the
mds_session_timeout is communicated via the mdsmap. The
mds_cap_revoke_timeout is known only to the MDS. Neither timeout results
in anything other than warnings in the current codebase.
There is also a third setting (mds_session_autoclose) that is also
communicated via the MDSmap. Exceeding that value (default of 300s)
could eventually result in the client being blacklisted from the
cluster. The code to implement that doesn't exist yet, however.
The current codebase doesn't do any real sanity checking of these
timeouts, so the potential for admins to get them wrong is rather high.
It's hard to concoct a use-case where we'd want to warn about these
events at different intervals.
Simplify this by just removing the mds_cap_revoke_timeout setting, and
replace its use in the code with the mds_session_timeout. With that, the
client can at least determine when warnings might start showing up in
the MDS' logs.

Wrap low-level rados APIs to allow ceph_volume_client to get, put, and

cephfs driver to store config data in a shared storage to implement
highly available Manila deployments. Restrict write(put) and
