Refine new UI changes to operations

UI changes:
  Operational item indicators are now colored cyan or green depending
  if the operation running was interrupted or completed successfully.

  The Summary Of Operations table no longer shows the number of issues
  an operation may have, instead, displaying whether the operation was
  interrupted or completed successfully in its place.

  If a user hits Control-C (or sends SIGINT), the UI cleans up the
  current operation, and let's the user know that Control-C was
  received, much like one would expect with an operation completed.
