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.

Setting the cluster_down flag will now set all active MDS
to standby and clearing it will restore the previous max_mds.
Changing max_mds when the cluster_down flag is set will clear the
flag automatically.

This parameter has the following 2 advantages:
1. FUSE(version > 2.8) the default single IO write size is 128k (controlled by max_write), if I use bs=4M in the FIO tool test,
you will find that 4*1024k/128=32 is needed, ie 32 IO operations are needed . If I adjust max_write to 4M,
only one operation is needed, which greatly improves the write performance of cephfs during fuse mount.
Of course, the above implementation requires libfuse and kernel fuse to support.
2. In addition, we can also limit the single IO write size by setting max_write to less than 128K.

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.

Since kraken, Ceph enforces a 1:1 correspondence between CRUSH ruleset and
CRUSH rule, so effectively ruleset and rule are the same thing, although
the term "ruleset" still survives - notably in the CRUSH rule itself, where it
effectively denotes the number of the rule.
This commit updates the documentation to more faithfully reflect the current
state of the code.
