Goal:

• We want to identify the hostname or fqdn as a display name so that customers can more easily identify the systems that are reporting usage when it is viewed in subscription-watch. The value for the display_name label should be the hostname or fqdn as retrieved by subscription-manager.
  An example would be display_name=foo.bar.com

Acceptance Criteria:

A list of verification conditions, successful functional tests, or expected outcomes in order to declare this story/task successfully completed.

• Verify that the display_name label on the metric is populated with the  name of the system as returned by the "subscription-manager identity" command.
