# install_designate_backend - install any external requirements
# configure_designate_backend - make configuration changes, including those to other services
# init_designate_backend - initialize databases, etc.
# start_designate_backend - start any external services
# stop_designate_backend - stop any external services
# cleanup_designate_backend - remove transient data and cache
