doc/cephfs: mds default cache memory limit is now 4GB

Problem:
The MDS only stores the symlink inode's backtrace
information in the data pool. During disaster
recovery of the metadata pool by scanning data
pool, the symlinks are recreated as regular files.
Solution:
This patch stores the symlink target on the first
data object as an xattr for recovery.
MDS option:
The mds option 'mds_symlink_recovery' is introduced
which is enabled by default. Enabling the option
stores the symlink target.

Since 58eaa237b0, an MDS is only promoted if it is compatible with the
file system compat. The users may see persistent failed state even they
have enough standby daemons.

doc: fix `daemon status` interface (exclude file system name)
test: adjust mirroring tests for `daemon status` change
mgr/mirroring: `daemon status` command does not require file system name
Reviewed-by: Patrick Donnelly <pdonnell@redhat.com>
Currently, to recover a file system after recovering monitor store, you
need to stop all the MDSs; create FSMap with defaults using `fs new`
command; execute `fs reset` command to get the file system's rank 0 into
existing but failed state; and then restart MDSs.
Add 'recover' flag to the `fs new` command that sets the file system's
rank 0 to existing but failed state, and sets the file system's
'joinable' setting to False. Using the `fs new` command with 'recover'
flag gets rid of the steps to stop all the MDSs and execute `fs reset`
command when recovering the file system after recoving monitor store.

The change to doing sync I/Os when we're in NEARFULL conditions
apparently caught some folks by surprise. Add something to clarify that
to the kclient debugging docs.
Also, remove the incomplete sentence that follows it, which contains no
useful information.

File system will need to be recreated when monitor databases are lost
and rebuilt. Some applications (e.g., CSI) expect that the recovered
file system have the same ID as before. Allow creating a file system
with a specific ID to help in such scenarios. This can now be done by
the `fs new` command using the argument 'fscid' and 'force' flag.
Newer file systems will no longer have increasing IDs as a corollary.
