Align static template to runtestmanager

* Add gtw 122 for external net for offline static
* remove post test resources creation in offline static

* Add docker repo for gtw node on ovs and ctl01 on contral
  templates, as for tempest run we need the docker
  and better install it from mirantis repo then from unpredictable source
