Add Cockroach DB Container Support

[joelhess]

You have implemented a new container and would like to contribute it? Great! Here are the necessary steps:

• You have added the new container as a module in the testcontainers directory (such as testcontainers/my_fancy_container.py).
• You have added any new python dependencies in the extras_require section of setup.py.
• You have added the extra_requires key to requirements.in.
• You have updated all python requirements by running make requirements from the root directory.
• You have added tests for the new container in the tests directory, e.g. tests/test_my_fancy_container.py.
• You have added the name of the container (such as my_fancy_container) to the test-components matrix in .github/workflows/main.yml to ensure the tests are run.
• You have rebased your development branch on master (or merged master into your development branch).

I'm an engineer from CockroachDB - this looks good to me!

Please let me know if there's anything else that I need to do to get this merged. I'm trying to keep it up to date with Master at this point.

There a few more major-ish changes to prepare for v4.x (e.g. #296). I'd suggest not updating the PR until then (but thank you for putting the work in to keep it up to date). Shall I let you know when master is a bit more stable?

@tillahoffmann Is the Main branch ready enough to update this to the new patterns?

[tillahoffmann]

Yes, fingers crossed.
