Our listing of products and repos does not show the last date/time of a sync.

It is hard to determine when the product/repo was synced. Consider this example:

katello> product list  --environment Library
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
                                                                          Product List For Organization redhat, Environment 'Library'

 SYS0395     Red Hat Employee Subscription                                            2             Red Hat         None

katello> product list  --environment Stage

                                                                           Product List For Organization redhat, Environment 'Stage'

 69   Red Hat Enterprise Linux Server   2             Red Hat         None                     
 167  Red Hat CloudForms                2             Red Hat         None

So is the Red Hat CloudForms product up-to-date or not? I would suggest to replace Sync Plan column which is not as much valuable as Last sync.
