Starting in pike, tripleo cannot deploy ceph pools of differing PG values

[John Fulton]

Both ceph-ansible (default in pike) and puppet-ceph (default before pike) support defining a data structure mapping Ceph pools to be created and their respective PG sizes. For example, ceph-ansible can be passed the following and it will deploy ceph pools of differing PG values:

CephPools:
  - name: mypool
    pg_nume: 256
  - name: anotherpool
    pg_num: 64

For TripleO to take advantage of this feature the following needs to be refactored:

    Update CephPools format in the docker templates to fit ceph-ansible

    The format which ceph-ansible uses to describe the list of pools
    to be created in the cluster is different from the one which
    puppet-ceph uses; this commit updates the description and the
    the docker templates accordingly.
