    Fix support for cinder ceph rbd in Ocata

    As of Ocata, the ceph key used to access a specific Cinder
    Ceph backend must match the name of the key used by cinder,
    with an appropriate secret configured for libvirt use with
    the cephx key used by the cinder-ceph charm.

    Add support for the new ceph-access relation to allow
    nova-compute units to communicate with multiple ceph
    backends using different cephx keys and user names.

    The side effect of this change is that nova-compute will
    have a key for use with its own ephemeral backend ceph
    access, and a key for each cinder ceph backend configured
    in the deployment.
