    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.
