moved docker compose to infra/local!

[auroter]

Wilfredo and I pair coded to move the docker-compose into infra, so that we can simultaneously debug the platform-admin-api and the main api at the same time if needed. The readme has been updated to include the commands required in order to run and debug in this manner. See other PR:

String-xyz/string-api#102

To test: (Instructions are now also included in readme.md in the main API)

1. Ensure you have the platform-admin-api repo
2. On platform-admin-api repo, checkout task/sean/str-373
3. Make sure to copy .env.example into your .env. The .env.example was updated to reflect the correct postgres and redis values.
4. Ensure you have the infra repo
5. On the infra repo, checkout task/sean/docker
6. Ensure you have the string-api repo
7. On the string-api repo, checkout task/sean/docker-readme

You can run docker compose from any repo now, and it will compose string-api, platform-admin-api, postgres and redis.

Some initial sanitation: [do this from the infra repo]

1. cd local
2. docker compose down
3. docker system prune (/y)
4. docker volume prune (/y)

And then this can be run from any repo:
4) docker compose -f ../infra/local/docker-compose.yml up

You should automatically get console output from whichever repo you run the previous command from. To get live console output from the other repo:

1. docker ps to list the docker container names
2. docker logs [docker container name] -f
3. for example, docker logs platform-admin-api -f or docker logs string-api -f from a terminal in the repo you did not run the docker compose from
