Spot VMs - August 17th, 2023 [Feature]

## Feature **Generally available**: The Ops Agent (version 2.38.0 and later) now supports the automatic tracking of GPU usage metrics reported from the NVIDIA Management Library (NVML) for Linux virtual machine instances that have attached NVIDIA GPUs. Through an available integration with NVIDIA's Data Center GPU Manager (DCGM), you can also track metrics such as Streaming Multiprocessor (SM) block utilization, SM occupancy, SM pipe utilization, PCIe traffic rate, and NVLink traffic rate.
