[Pulp-dev] Integrating Katello with Pulp3 Recap

Some of the Pulp devs involved in the gap analysis put together this
roundup of the gap problem statements [0]. I've scheduled two calls so that
we can go over the problem statements to ensure a shared understanding, and
think of some possible resolutions. My intention for the calls is to
generate ideas and not decide on them. Final decisions and written recaps
will be sent to the list for additional input.

June 22nd: noon - 1pm UTC             <---- https://bluejeans.com/663034124/
June 29th: 12:30pm - 1:30pm UTC       <----


We'll send a round-up of the best options that come out of the call to the
list for discussion in roughly two weeks. Thank you to everyone who has
collaborated throughout this process so far!
