865708120f doc: remove references to default data/metadata pools 
These haven't existed since 0.84 -- the cephfs documentation

rados documentation.

19ee231115 ceph: adjust crush tunables via 'ceph osd crush tunables <profile>' 
Make it easy to adjust crush tunables.  Create profiles:

 legacy: the legacy values
 argonaut: the argonaut defaults, and what is supported.. legacy! (*(
 bobtail: best that bobtail supports
 optimal: the current optimal values
 default: the current default values

* In actuality, argonaut supports some of the tunables, but it doesn't
  say so via the feature bits.

5061481129 doc: correct meaning of 'pool' in crush 
This was recently made less confusing by renaming the default crush
'pool' type to 'root'. Use this terminology everywhere as well.
This was not in argonaut, so perhaps this should delay being merged.
