Description of problem:

The command 'katello org subscriptions' output header shows 'ProductName'.  However, there are no matching products by the name used (in the case of RHEL).  I believe the column is incorrectly named.  Perhaps it should simple state "Name" or "Subscription"?

Version-Release number of selected component (if applicable):

 * katello-0.1.238-4.el6.noarch
 * katello-cli-0.1.54-2.el6.noarch

Steps to Reproduce:
1. katello -u admin -p admin product list --org=ACME_Corporation -g
2. katello -u admin -p admin org subscriptions --org=ACME_Corporation -g
 
Actual results:

> katello> product list --org=ACME_Corporation -g

    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    Does not match the name of any of the products listed earlier

Expected results:
