I just realized this was unmerged, but I already merged the packaging client bindings. I still assume we want to get it in this week, so I'm not going to revert just yet. Please let me know if it goes otherwise.

[ianballou]

I'll remove the requirement that we should test with the RPMs -- installation from pypi should suffice

Smoke tested the updated pulp versions and am able to do everything as usual.
Tested repo workflows, CV workflow, host workflows, import/export. Orphan deletion etc and everything seems to work great in my testing.

ACK 👍🏼
