Migrate CI to GitHub Actions

[mpeyper]

Describe the feature you'd like:

The queue times on travis-ci are just getting stupidly long at this point and I gave GitHub Actions a go in a personal project recently and it was really nice. I'd like to convert this project over to using it instead.

Suggested implementation:

Read the docs, implement the config.

Describe alternatives you've considered:

There's plenty of other CIs out there, but I don't see any reason to consider other alternatives at this stage. Happy to hear suggestions though.

Teachability, Documentation, Adoption, Migration Strategy:

yo kcd-oss would make this easier, though you'd have to change some of the scripts unless you also plan on migrating to kcd-scripts (see #498).
