    upgrade: preserve glance-registry for Queens

    The glance-registry daemon was deprecated at Queens, but was still
    installed for the Queens charm release; ensure that any re-install
    of paste.ini files accomodates this as part of the charm upgrade
    process, resolving issues with glance-registry not running due to
    missing paste configuration files.
