Code Issues Proposed changes

Various deploy from source changes and c-h sync

Browse Source 
* openstack-origin is no longer required when using openstack-origin-git.
* Drop kilo from openstack-origin-git default values because upper
  constraints doesn't work in kilo for openstack-dashboard and glance.
* Add flag to allow for disabling upper constraints when using
  openstack-origin-git with user-specified git repositories.

Returns the number of placement groups which should be specified when

The number of placement groups are calculated using the following:
(Target PGs per OSD) * (OSD #) * (%Data)
----------------------------------------
(Pool size)
Per the upstream guidelines, the OSD # should really be considered
based on the number of OSDs which are eligible to be selected by the
pool. Since the pool creation doesn't specify any of CRUSH set rules,
the default rule will be dependent upon the type of pool being
created (replicated or erasure).
This code makes no attempt to determine the number of OSDs which can be
selected for the specific rule, rather it is left to the user to tune
in the form of 'expected-osd-count' config option.

where related charms requiring pools has not been upgraded to
include an update to indicate their relative usage of the pools.
