Previously, KubernetesCompute only used GPU from the first offer to set node affinity, and if that type of GPU was not available (e.g., another job or even some non-dstack pod had already taken it), the job eventually failed with FAILED_TO_START_DUE_TO_NO_CAPACITY, even if there were other GPUs matching the run spec requirements.
Now, we inspect all nodes to request all suitable GPUs (any of).
In addition, we now use upper bounds of Ranges (CPU, memory, disk) as limits except for GPU, which cannot have request =/= limit (as it cannot be overcommited).
