feat: containerized apps

[dopry]

Description of the Change

• add Dockerfile to build the tests/app/idp
• add Dockerfile to build the tests/app/rp
• add a docker compose file to build and start instances of the idp and rp

You can test this setup with
docker-compose up

This could be nice for testing new branches with the following

docker-compose down -v # remove existing env docker-compose build # rebuild the images docker-compose up # spin up the docker compose environment 

You should be able to goto http://localhost:5173 and http://localhost:8000 to access the compose instances.

This is a precursor to publishing the test IDP as a container via docker hub. I hope making a Django based IDP more accessible will help grow our contributor and user community.

@dopry this looks like a cool idea. Sorry for the delay in looking. Documentation could be short and simple -- "use docker-compose up to start up an OAuth server".

I had started doing something similar here https://github.com/n2ygk/dot-tutorial using Heroku and an attempt to try out some OIDC certification testing. See the notes

There's a bunch of conflicts now -- maybe I merged something prematurely?

[dopry]

No worries. I'll update it when I get a chance.

@n2ygk This should be rebased and ready for a cursory review.

Looks good. I was able to fire up the docker container and did some minor testing (just a GET http://localhost:8000/o/.well-known/openid-configuration and a few of the links there)

Regarding future documentation, perhaps update https://django-oauth-toolkit.readthedocs.io/en/latest/tutorial/tutorial_01.html or add a new chapter to the tutorial?
