Description of problem:
When A user is on a Roles > Permissions page (either global or org) or Roles > Users and begins tabbing through the elements, it becomes evident that user cannot tab through all elements on page, particularly the 'footer' buttons (add permission, edit role, remove role)
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Navigate to any of these pages, particularly to an Create or Update operation, as applicable.
2. Hit tab repeatedly while cycling through all available elements
3. View results
Tab cycles avoid the buttons at the bottom of the UI
User should be able to tab to the footer buttons.
Adds action bar items on Roles page to tab index such that they can now be tabbed through. The enter button will now cause the action bar event to trigger for the focused button.
