Docker-compose (#325)

* Stop failing if config is missing, hard to debug docker

* Changing message to reflect new behaviour

* Adding docker compose for eaiser development setup

* Docker-compose starting mosquitto in a container that mpp-solar container can connect with

* Setting the entrypoint so mpp-solar starts automatically in daemon mode.

* Updating the ignore file to exclude mosquitto files

* Reverting the behaviour if no config file

* Adding development Dockerfile and docker-compose yaml
