Change order of if-elif conditionals in set_openstack_containers temp…

…late

To update both container tags and ansiblee RELATED_VARS of openstack-operator
in the same set_openstack_containers role run both cifmw_set_openstack_containers_tag
and cifmw_set_openstack_containers_overrides are defined.
cifmw_set_openstack_containers_overrides if conditional must be checked later,
because otherwise container_tags modifications are all skipped.
