CE-2812: Replace fetching data banner with linear progress

Before job is started lineear progress is displayed instead of a banner saying Fetching data. Once the job is queued then a banner is visible stating the current job step (as before). Should correspond to stepper state, but they are out of sync. This issue is reported as a bug and out of this scope.

To test: Deploy or Undeploy one of our test IOC: s in Demo
