Instead of having the information about which base behaves which way with regards to support, pebble, plugins, etc, have a single "bases" module that serves as an authoritative source for all base-related knowledge. The idea is that someone can look at this single module and have a full view of how Rockcraft's behavior changes depending on the project's base. - [ ] Have you followed the guidelines for contributing? - [ ] Have you signed the [CLA](http://www.ubuntu.com/legal/contributors/)? - [ ] Have you successfully run `make lint && make test`? ---
