--------------------------------------
This story could change once Mesos gets pods support and we start launching
tasks in subcontainers.
> Account for thermos executor overhead in reported CPU usage to user

>
> The default .25 CPU overhead taken for thermos can be hugely impactful on
> clusters with many tasks and it's not reported to the user in the web UI.
> Ideally the resources used by the cluster should be reported accurately. We
> ran into a case where we could not launch jobs even though we thought we had
> plenty of free cores.
> Alternatively, the thermos overhead could be removed completely. I think it's
> confusing personally.
