Ceph MDS pools creation fails

[Giulio Fidente]

When deploying with ceph-mds, the deployment fails on task: TASK [ceph-mds : create filesystem pools] with:

    The task includes an option with an undefined variable. The error was: 'dict object' has no attribute 'pg_num'

    The error appears to be in '/usr/share/ceph-ansible/roles/ceph-mds/tasks/create_mds_filesystems.yml': line 24, column 11, but may
    be elsewhere in the file depending on the exact syntax problem.

    The offending line appears to be:

          block:
            - name: create filesystem pools

    Updates the cephfs_pools format to match that of openstack_pools

    We did not keep the cephfs_pools format updated as we did with
    openstack_pools; ceph-ansible rc11 has a backward incompat issue
    with the old format.
