If nova isn't creating accelerator resources managed by cyborg, I have 
no idea why nova would be doing quota checks on those types of 
resources. And no, I don't think adding a scheduler filter to nova for 
checking accelerator quota is something we'd add either. I'm not sure 
that would even make sense - the quota for the resource is per tenant, 
not per host is it? The scheduler filters work on a per-host basis.

Like any other resource in openstack, the project that manages that 
resource should be in charge of enforcing quota limits for it.
