These commands now destroy the containers and volumes of the
specific service being interacted with.
Prior to this the mediawiki destroy command would just run
down on the whole docker-compose setup (as it was the only service).
But now we need to be a little more selective.

docker-compose doesn't provide commands to do all of this out of
the box, which is why a docker command is needed to destroy specific
named volumes for the services.
