Testing mjolnir with docker

At the moment a test environment for mjolnir can be setup by running ./mjolnir_testing.sh from the parent directory. This script will use the docker-compose.yaml in the parent directory.

This sets up synapse container with a user for mjolnir to use. The container for mjolnir, creates and joins the moderation room which has to be specified with an alias in the config under managementRoom. Eventually this setup should be moved to a testing module.
