hxldash-docker docker-compose.yml file otimized for local development (with minimal documentation)

[fititnt]

This issue is about write both an docker-compose.yml and the bare minimum documentation to help who just want to run a local copy of the hxldash (like a fork or a simple downloaded folder) and be able to test changes on the front-end part of the code.

Humm... It works from http://127.0.0.1:8000 inside the container, but it refuses from outside http://127.0.0.1:8000 with default port forward, the container does not accept. Makes sense.
