Simplify the local development Experience and document it

[asaikali]

There are no instructions how to do local development for this application locally. Also there are docker-compose files all over the place that seem out of date.

Simplify the development experience to be the following

1. checkout code from git
2. load into vscode
3. run docker-compose up to launch and required services
4. run individual apps
5. use browser to visit the applications and everything should just work
