27f06346e2 doc: fix formatting on PG recommendation 
Previous commit (047287afbe) broke
formatting on the formula, and also made mixed formula and text oddly,

Add the note about the power of two to the following paragraph

047287afbe doc: Add "nearest power of two" to PG rule-of-thumb 
Following an IRC discussion, it emerged that it would be helpful
to explain the merit of choosing a number of PGs per pool that is
a power of two, to keep PGs at roughly equal sizes in case of
PG splits.

See http://irclogs.ceph.widodh.nl/index.php?date=2014-03-12 for the
original discussion.

724ad02584 doc: update the operator create pool reference 
Include erasure code information. A choice is made to display properties
that should be documented as part of the erasure code plugin
interface (erasure-code-k for instance). However, there only is one
plugin at the moment. Furthermore, erasure-code-k and erasure-code-m are
the two properties that the system administrator will want to tweak when
playing with erasure coded pools for the first time. It is probably
better to document them in a very visible place for this reason.

If --osd-pool-default-crush-rule is set it takes precedence over

displayed.

Replace the manually crafted ruleset in OSDMap::build_simple_crush_map*
with calls to add_simple_ruleset. The generated ruleset do not have the
same behavior but that presumably do not cause any backward
compatibility problem because they are only created when a new cluster
is being initialized.

The prototypes of OSDMap::build_simple* are modified to allow for a
return code and display of a human readable error message.

The --osd-min-rep and --osd-max-rep configuration options are removed :
they were only used in the code that was removed.
