Bug 860452

Description of problem:
Delete resource artificats like org/env/provider/system groups doesnot delete permission which have tags associated with those permissions

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


How reproducible:
Always

Steps to Reproduce:
1. Login as admin
2. create a custom provider X
3. create a role Y
4. Add a permission to  role Y to read/modify provider X
5. Delete provider X
6). Expand Role y

Actual results:
Notice that the permission associated to provider X still exists

Expected results:
The permission associated to provider X must get wiped out since provder X was deleted.

Additional info:
Similar case for Org/Environment/System Groups (the tags end up staying in the permissions even though the resource themselves were deleted.)
