Add RBAC and Tagging Support to Ansible Repositories

[hstastna]

Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=1526217
Needs to merge with: [SOLVED/merged]
ManageIQ/manageiq#17083 (tagging support to main MIQ repo)
ManageIQ/manageiq#17091 (RBAC support)

---

Done:

• add Policy toolbar button to access tagging in Automation > Ansible > Repositories
  (Policy > Edit Tags)
• add tagging_edit and tag_edit_form_field_changed to routes to enable tagging for Ansible Repos or for proper rendering of tagging screen
• add calling tag method to button method in ansible credential controller and also small refactoring of button method, in that controller
• display tags in the table in summary page of any credential
• make tagging work also from summary page of any credential
• check if RBAC works - it should work after merging Add ConfigurationScriptSource to RBAC manageiq#17091
• spec test for button method in ansible repository controller

Before:

After:

Note:
How to check RBAC support (one of possible scenarios):

1. as an admin, tag some repo(s) from Automation > Ansible > Repositories,
   remember those tags
2. in Configuration > Access Control > Groups, create a group so that under Assigned Filters in the first tab called My Company Tags, you choose the same tags as tags from step 1.
3. set EvmRole-administrator as a role of that group (not super administrator!) and save the group
4. create a user with that group from step 3.
5. logout and login as the user from step 4.
6. go to Automation > Ansible > Repositories and you should see only the repositories with the same tags as from step 2.

@h-kataria @dclarizio @martinpovolny Adding RBAC and Tagging Support to Ansible Repos done so now I would need some review. Thanks so much! :)

looks good, ready to merge once Travis is green.

@himdel can you look at Javascript test failures.

@hstastna Travis is failing in gaprindashvili branch. Please take a look.

  1) AnsibleRepositoryController#button editing an existing repository redirects to action edit
     Failure/Error: ApplicationRecord.uncompress_id(cid)

@simaishi If is failing because I've written spec tests for master branch, for the newest code and also for the parts of the code I haven't written. The older code is different, it looks like it still uses compressed ids which were, I think, removed from the newest code. And that's not related to this PR. Anyway, I will try to fix that failing spec test for gaprindashvili branch

[simaishi]

Yes, I realized that code has changed between master/gaprindashvili. But since that failing test was added in this PR, I've added the info here 😄 Thanks for fixing!

[hstastna]

@simaishi So finally it was not hard fix: #3563
