Description of problem:

After uebercert generation there is created a special consumer created and subscribed to a special uebercert product. These are mostly (or entirely) used to generate entitlement certificate that allows access all the content of the owner. There is a problem however when deleting owner with such a uebercert generated.

Uebercert porduct and pools can't be filtered by owner and when trying deleting the consumer we get

"Runtime Error null at org.candlepin.service.impl.DefaultIdentityCertServiceAdapter.deleteIdentityCert:67"

Since this ueber-consumers and products are mostly internal thing of CP, I suggest CP to deal with it without any requirement on API calls from client (Katello in this case).

Version-Release number of selected component (if applicable):
candlepin-0.5.10-1

How reproducible:
always

Steps to Reproduce:
1. create owner
2. generate uebercert
3. delete owner

  
Actual results:
ERROR: update or delete on table "cp_owner" violates foreign key constraint
"fk_pool_owner" on table "cp_pool"
  Detail: Key (id)=(4028fa81351962fc013519686cd30003) is still referenced from
table "cp_pool".

Expected results:
Owner deleted successfully

Additional info:

This quite a big issue on Katello side
