45caf26140 mds: improve eviction usability and update docs 
The "session ls" and "session evict" are now
"client ls" and "client evict" (the old ones
are still there for backwards compatibility).

The automatic client eviction now emits
cluster logs that call the client by its
friendly name (usually the hostname).

ad1882350d mds: remove "mds log" config option 
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.

e0bbc70467 client/Client.cc: add feature to reconnect client after MDS reset 
Client.cc marks session as stale instead of reconecting after received
reset from MDS. On MDS side session is closed so MDS is ignoring cap
renew. This adds option to reconnect stale client sessions instead of
just marking sessions stale.

cb86740a5f cephfs: Permit recovering metadata into a new RADOS pool 
Add a procedure that permits reconstructing metadata in a potentially
damaged cephfs metadata pool and writing the results into a
freshly-initialized pool that refers to the same data pool. Add option
flags to override checks that would ordinarily prevent this and add
options to the recovery tools to write output to a separate pool instead of
the one selected for recovery. See docs/cephfs/disaster-recovery.rst for
details.
