Try to upload cirros after each deploy

- take controller uid from nodes attribute which is present for every
  generated node
- credentials will be obtained from openrc file on controller
- remove check for cluster status after deployment

This way we will try to upload TestVM image every time after deployment,
and if there is no TestVM image present in glance
we will add it
