> In the present code cleaning worker vms after a timeout is disabled, with the documented
reason that there is no API to query for related tasks in vcenter. ACS has an expiry time
for jobs and a cancel time for jobs.
> - Jobs that take longer then the expiry time will have their results be be neglected.
> - Jobs that are cancelled are forcibly removed after the cancellation expity time.
> Any worker remaining after expiry+cancellation will surely be stale and can be removed.
> As some administrators may not want this behaviour there will be a setting which by default
is false that will guard against cleaning stale worker VMs.
> Stale worker VMs will be cleaned after 2 * (expiry-time + cancellation-time) as a safe
margin.
> related settings:
> job.expire.minutes: 1440
> job.cancel.threshold.minutes: 60
> vmware.clean.old.worker.vms: false (new)
