Updates docker version to 19.03.11
Part of the ~"group::configure" dependency updates: gitlab-org/configure/general#65 (closed)
Includes a minor refactor in which, before we had to update the version in 3 places, now we only update in 2. It also only associates the docker service with the jobs that need it. The test
job does not need it.
