I'll work on YETUS-1063 so that things make more sense. But in short,
Yetus' "docker-cleanup --sentinel" will purge container images if they are
older than a week, then kill stuck containers after 24 hours. That order
prevents running jobs from getting into trouble. But it also means that in
some cases it doesn't look very clean until two or three days later. But
that's ok: it is important to remember that an empty cache is a useless cache.
Those values came from experiences with Hadoop and HBase, but we can certainly
add some way to tune them. Oh, and unlike the docker tools, it pretty much
ignores labels. It does _not_ do anything with volumes, probably something we
need to add.
