Description of problem:
katello:delete_orphaned_content triggers queries on the DB to identify what are the orphan units to be removed. However, such query is not efficient on systems where table katello_repository_rpms is big.
Query is slow, consumes a lot of cpu and the task may take long time to run. Examples showing the query and long it took to run:
