Add the epcon dev role for test

@artcz, I have been trying different approaches for Ansible with Docker for this case.

The thing is I prefer to see Ansible as a tool only for deployment (setup and launch), but not for management. Hence, what I am doing in the chatbot role is to generate/build a docker-compose.yml file to later on use for launch and management of the containers within the server.

My idea of the website role (or roles) should do:

• Install the dependencies for DB and website,
• Add to the docker-compose file the website container, DB container, volumes, and network,
• Setup the volume and initialize the DB server container,
• Setup the volume and initialize the website container.

For the dev stage, it should clone the ep20XX-dev branch.

Maybe later we could have separate more specific/generic roles, e.g., DB and website.

I think a better approach is to have the whole docker-compose/Dockerfiles setup in a separate repository. Generating those files will be a pain and hard to maintain
