Add /api/ctf/start and /api/ctf/stop routes

[mradigen]

This PR adds the following:

• Starting and stopping of Docker containers
• Allow for response messages to be configured from config.py
• Tortoise Models for Container and CTF
• Restructure DB to run asynchronously with FastAPI without multiple event loops
• Update docs

I could not add tests cause I was unable to figure out how to run asynchronous tests with pytest.

Not sure why mypy is considering image_config["ports"] as a str when it is a dict. Additionally it seems that the docker module doesn't have a py.typed, hence mypy throws an error for that.

Also run, tox run -e black
In order to fix the type errors you will have to jump through some hoops, it should become easier to pass through after #7

[WizzyGeek]

Everything looks good, except the docker client being initialised before the app runs, in the future it might break if someone decides to change the eventloop, but we can ignore that if it works rn

[WizzyGeek]

oh yah, get atleast 3.11 to pass before merging, for any type issues you can't resolve after #7 lemme know I will do a PR to your fork

[WizzyGeek]

I think we need safe=True here?
