0d094f8f52 doc/cephfs/dirfrags: clarify the unit of threshold limits
Rationale: There are many threshold limits for split and
           merge in this doc that just says like:
           "A directory fragment is eligible for splitting
           when its size exceeds `mds_bal_split_size`
           (default 10000)". Need to clarify what 10000 actually
           means. This applies to all other such entries in this
           doc.

cephfs: kill allow_dirfrags
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.

mds: obsolete MDSMap option configs
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
set` where missing.
