Granular deployment.  Deployment could be break down into following steps:     a.  ir-installer --dry-run (generate install.yml setting file)     b. run ansible tags in following order:         * undercloud         * virthost,backup         * instack         * images,introspection,tagging         * overcloud     To do that we need to move tasks from undercloud tag to images tag,     since the facts which were created in undercloud step are no     longer available in next run with next set of tags.
