commit 15ed2c1489957595176a1e4de8870e189328c7d2

Added check for `--isolation=gpu/nvidia` in order to autodiscover GPUs.
We add this check because we decided it makes sense to only do
autodiscovery of GPUs when this isolator is turned on (unlike for
CPUs, memory, and disk where autodiscovery happens by default). We
decided to take this approach, because GPU support is still
experimental, and is only known to work well if this isolator is
enabled. We didn't want to start advertising GPUs in our resource
offer and have people attempt to use them in scenarious we haven't
considered yet. In the future we may support other use cases, but for
now we are being cautious.

> 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.
