We want to use stop_grace_period to manage gerrit service stops. This
feature was added in docker-compose 1.10 but the distro provides 1.5.
Work around this by installing docker-compose from pypi.
This seems like a useful feature and we want to manage docker-compose
the same way globally so move docker-compose installation into the
install-docker role.
New docker-compose has slightly different output that we must check for
in the gitea start/stop machinery. We also need to check for different
container name formatting in our test cases. We should pause here and
consider if this has any upgrade implications for our existing services.

This ensures that we cleanup images that are superceded and no longer
necessary. We do this to avoid filling the disk with docker images.
Note that we use the -f flag to avoid being prompted by docker image
prune for confirmation.

This will make sure that the latest relevant images are in the
local image storage, and therefore, will cause docker-compose up
to recreate containers when the images are updated.
