Assume we have 14 GPUs.
If there are YARN GPU requests for, say, 5 GPUs but currently, 12 of the GPUs are allocated.
Hopsworks will show that there are 12 allocated GPUs and 5 queuing. It looks like the number of installed GPUs has decreased. We should also show that there are 3 available GPUs. Maybe an extra line is needed for this that is only shown when we have queued requests, but free GPUs.
