Duplicate feature identifiers causes feature privileges to change

[kbrock]

In https://github.com/ManageIQ/cfme/issues/1802 we introduced a number of new features. Unfortunately, it introduced a number of feature with the same identifier.

Our seeding process uses identifier as the unique id, and it is swapping these features around on primordial seeding (every worker/appliance boot). Said another way, a feature's primary id changes, and a user's privileges change when workers start.

We either need to improve the seed process, or we need to change the identifiers to be unique.

feature	count
ab_group_new	2
ab_group_edit	2
ab_group_delete	2
ab_group_reorder	2
ab_group_edit	2
ab_button_new	3
ab_button_delete	2
