Issue MESOS-5257: Add autodiscovery for GPU resources
Right now, the only way to enumerate the available GPUs on an agent is to use the `--nvidia_gpu_devices` flag and explicitly list them out. Instead, we should leverage NVML to autodiscover the GPUs that are available and only use this flag as a way to explicitly list out the GPUs you want to make available in order to restrict access to some of them.
