[Cloudkitty][ptg] CloudKitty Wallaby PTG outcome

Hey people, Thanks to everyone who attended the CloudKitty PTG sessions, we covered a lot during the meeting. The Etherpad is available at [1].

In Etherpad [1], I added the notation "TODO(XXX):" in the topics we discussed, that require effort from someone. The work can be either writing a use case story, developing extensions/features, or creating test cases. Therefore, if you are interested in working with that item, do not hesitate and put your name there. Anyone in the community is welcome.
