Looks like leftover docker images

Have dont a it of a clearout but still lots of images left. @smlambert would you expect machines used for the external testing to leave lots of images around between runs and if so do you know the total requirements for the space in /var/lib/docker? We may have to remove the docker tag from this particular machine as it's a bit more space limited than the ones at some of our other providers :-)

[smlambert]

We clean up the machine at the end of each test run, but if the run is aborted, we are unable to clean it up. I am aware there have been cases like this (when others pre-emptively kill jobs). We plan to add a 'docker prune' step (adoptium/TKG#45), but yes, if a machine is short on space, you may wish to remove the tag.

On the basis that we're no longer short on Linux/x64 machines to run tests on I'll do that for now and close this/ sw.tool.docker removed from test-scaleway-ubuntu1604-x64-1
