    Tidy ceph backend configuration

    Drop generation of upstart override file and /etc/environment and
    scrub any existing charm configuration in these locations from
    an existing install.

    These where required way back in the dawn of time when ceph support
    was alpha/beta in cinder.

    Provide backend specific configuration file path, allowing multiple
    ceph clusters to be used with a single cinder application.
