Change barbican pillars in runtests

Currently we have 3 cases:
* barbican is disabled
* barbican is enabled but integration is disabled
* barbican and integration is enabled

So in this patch:
* strict tgt to ctl01
* get data separately for barbican service
  and for it integration
* Add if for command as image sign is
needed only when integration set in true
