    Allow enabling custom backends with manila

    It is possible to provide the config settings
    to add an arbitrary and unmanaged backend to Manila
    at deployment time via Heat environment files. However,
    puppet-tripleo doesn't support extending the
    list of enabled backends. Add this capability.
