Goal:

• We want to identify the installed products so that we can differentiate the metered product. In order to do this the host-metering tool can extract the product IDs from the "subscription-manager list --installed" command. The value for the product label should be a comma separated ordered list (for deterministic sorting; numerical would make the most sense).
  An example would be product=69,204.

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 product label on the metric is populated with the installed product IDs as found by subscription manager and that these IDs are in a numerical ordered comma separated list.
