the singular reason to switch Windows machines from VBox to Docker, which is unnecessary anyway, would be to shut you up.

web and scheduler: enable plan classes for BUDA

If you make a variant of a BUDA app for a plan class
(e.g. NVIDIA GPU with CUDA)
this ensures that jobs submitted to that variant are sent
only to capable hosts,
and that the host usage and projected FLOPS are set correctly.

On the web side, we add a <plan_class> element to workunit.xml_doc.
This gets sent to the scheduler.

On the scheduler this required some reorganization.
As the scheduler scans jobs, it finds and caches
a BEST_APP_VERSION for each app.
This contains a HOST_USAGE.

In the case of BUDA, the host usage depends on the workunit,
not the app version.
We might scan several BUDA jobs
they'll all use the same APP_VERSION,
but they could have different plan classes
and therefore different HOST_USAGE.
