Pulp

http POST :24817/pulp/api/v3/orphans/ content_hrefs:= []

Enable a POST call to the orphans endpoint that would accept a list of content_hrefs to purge.

1. A task will be triggered and will call into orphan_cleanup(). Instead of looking for all of the orphaned content across pulp , it would just instead work with the list if hrefs provided( in case the list of content_hrefs was provided).
2. The timestamp_of_interest on the content will be honored and if there was specified a Content unit that is not an orphan - it will be ignored.
3. Only content that has version_memberships__isnull=True will be purged.
