Set up GitHub actions for running tests

This is a first stab at setting up GitHub actions for running the
catalog-api CI tests. At this point I've just migrated the old Travis-CI
setup to a GitHub actions workflow. Not sure if I need the Docker hub
login anymore? I'll try it without and see what happens.
