Create unit tests and a testing pipeline to interact with platforms

It would be ideal to deploy a CTF platform instance using ci/cd and dynamically interact with it to test our code.
First, we need to setup the platform locally (create users, challenges, etc.), then make a snapshot (e.g., for CTFd that would be a DB export) and put it somewhere. When the workflow job runs, it will fetch the config and deploy a platform instance to run the tests on.
