This commit adds a Docker infrastructure that is ready for production use. It is meant to simplify the deployment of OSEM for everyone who wants to host their own instances. It includes many features like data persistence, automatic secret key generation and persistence and automatic database initialization and upgrading. This should make updating the Docker container as easy as possible.
