#29 Improve Docker Compose workflow

[OhhBilboBaggins]

This PR makes it so that bootstrapping a local development environment for terra_algo_backtest is as close to simple as it can be with our current CI / CD pipeline, regardless of the host environment. Now all that should be needed to run the project is two simple docker compose commands.

Testing

docker-compose up prerun
docker-compose up

Intended Results

• [ ] A docker image and container labelled terra_algo_backtest-prerun should be generated, as well as a .env file in the project root that contains dynamically generated environment variables for the ENV_TAG, DEPS_TAG, and BUILD_TAG keys.
• [ ] A docker image and container labelled terra_algo_backtest-env with a tag matching the ENV_TAG value in the .env file should be successfully created.
• [ ] A docker image and container labelled terra_algo_backtest-deps with a tag matching the DEPS_TAG value in the .env file should be successfully created.
• [ ] A docker image and container labelled terra_algo_backtest-build with a tag matching the BUILD_TAG value in the .env file should be successfully created.

Notes

If you need to regenerate the .env file for whatever reason, you can do so by simply running the following command:

docker-compose up prerun
