This commit adds a lot of new code including the mailman's web frontend. It includes a configuration file which can later be configured to run required configs. Also, the docker-compose file spins off the containers, sets up appropriate volumes and links.
Mailman3 Core Docker Image
To run this container, you need a valid configuration at
/opt/mailman/mailman.cfg on your host. When you spawn off this container, you
must mount /opt/mailman to the container. Mailman's var directory will also
be stored here so that it can persist across different sessions and containers.
It is not advised to run multiple mailman processes on the same host sharing the
same /opt/mailman directory as this will almost certainly be dangerous.
