aea9fa01ae doc: globally change CRUSH ruleset to CRUSH rule 
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.

mds: remove deprecated commands from docs 
This mostly is just removing the commands from the man page ceph(1). I
