Add ceph-pool-weight option for calculating pgs

Browse Source 
Provide the weight option to the Ceph broker request API for requesting
the creation of a new Ceph storage pool. The weight is used to indicate
the percentage of the data that the pool is expected to consume. Each
environment may have slightly different needs based on the type of
workload so a config option labelled ceph-pool-weight is provided to
allow the operator to tune this value.

your ceph cluster).
ceph-pool-weight:
type: int
default: 5
description: |
Defines a relative weighting of the pool as a percentage of the total
amount of data in the Ceph cluster. This effectively weights the number
of placement groups for the pool created to be appropriately portioned
to the amount of data expected. For example, if the compute images
for the OpenStack compute instances are expected to take up 20% of the
overall configuration then this value would be specified as 20. Note -
it is important to choose an appropriate value for the pool weight as
this directly affects the number of placement groups which will be
created for the pool. The number of placement groups for a pool can
only be increased, never decreased - so it is important to identify the
percent of data that will likely reside in the pool.
