As part of the Python 3 conversion we made a number of infrastructure changes such as moving from nosetests to pytest and adding Dockerfiles so we can deploy Docker images. There are a couple more

• All of our projects should use Github Actions instead of Travis CI.
• All of our Docker builds should use a common set of image names and build images with similar capabilities.
• In particular, it should be possible to use circulation and metadata images as development environments, along the same lines as what Nick set up for library_registry. This will make it much easier to get started with development.

The Python 3 work itself was urgent but this is not; we can come to it once we're ready to do some more foundational work.
