Change Details

While creating disk usage dashboards in T327435 it was noticed that `/var/lib/docker` is inside the root volume of gitlab-runner hosts (Trusted Runner). The default partman config has a rather small root partition (~70GB) and a bigger `/srv` partition (~600GB). We should create a dedicated partman config with a bigger `/var/lib/docker` to use the disk space more efficient for docker caching. Furthermore this would also prevent a full root partitions due to a lot of docker data. Hosts to reimage: [x] gitlab-runner1002 [x] gitlab-runner1003 [] gitlab-runner1004 [] gitlab-runner2002 [] gitlab-runner2003 [] gitlab-runner2004 Steps after reimage is done: [] increase `profile::gitlab::runner::docker_gc_*_water_mark` matching new disk size for Trusted runners
