Remove abandoned deliverables

Following the victoria-2 consistency check, remove victoria
deliverable files for a number of recently-abandoned repositories:

- paunch (marked deprecated in victoria, Jun 10)
- puppet-congress (retired on Jun 21)
- mox3 (retired on Jun 18)

Additionally, mark tripleo-repos (marked release-management:none)
as abandoned since it's cycle-independent.

Note that mox3 had a victoria release before being retired.
