We need a rake script that populates PRN for the repository version href fields. The initial migration went in as part of PR here: https://github.com/Katello/katello/pull/11503
This rake script needs to be called as a post upgrade task.

We have one field https://github.com/Katello/katello/pull/11503/files#diff-719139140171ac86b6eaf91647a0710f859473e53713d348f4abd159f26cf9ddL25 which needs to be populated.

We also need to make sure the not null constraints and indexes that are commented as part of the PR https://github.com/Katello/katello/pull/11503/files#diff-f3dbfa6b9f871ba388a5934d047872ffbabbe6b152324fc609132b39a3ddaa09R294 get uncommented once we start populating these for new records.
