Description of problem:
The organization removal task is not atomic:
If the organization has some managed resources associated, its removal will fail:

# hammer -u admin -p changeme organization delete --id 3
[............  ] [95%]
foo is being used by a hidden Host::Managed resource

However, Candlepin manages to remove the Owner:

This leaves satellite in inconsistent state, where candlepin no longer recognizes the org while it still exists in the DB. Any action involving this organization (even uploading a manifest for other org) ends up in error:

Version-Release number of selected component (if applicable):
6.2.0 bet (GA14.1)

How reproducible:
always

Steps to Reproduce:
1. create an organization
2. have a host assigned to this org (you can use the satellite host itself)
3. try to delete this organization (this should fail)
4. try to create a new org and upload a manifest to it (this fails due to missing org above))

Actual results:
- candlepin removes the Org

Expected results:
- candlepin does not remove anything if the removal results in error in satellite (the removal task should be atomic)
