Drop accelerator metrics and nvidia implementation

[liggitt]

This capability is unused as of Kubernetes 1.25+ (see kubernetes/kubernetes#114204 (comment) and https://github.com/kubernetes/enhancements/tree/master/keps/sig-node/1867-disable-accelerator-usage-metrics)

That means nvidiaManager was always a no-op implementation in Kubernetes 1.25+

This drops the nvidia implementation, collector, and AcceleratorUsageMetrics stats type, which also allows dropping the github.com/mindprince/gonvml dependency, which some license scanners were unhappy with (xref https://groups.google.com/g/kubernetes-sig-architecture/c/dsMVIdPPUK8/m/u3ZjJtcnBwAJ?utm_medium=email&utm_source=footer)

Hi @liggitt. Thanks for your PR.

I'm waiting for a google member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

Thanks @liggitt, I agree it makes sense that we can drop accelerator metrics after k8s has deprecated in-tree accelerator metrics and drop this dependency.

For cAdvisor users, we can recommend users to use https://github.com/NVIDIA/dcgm-exporter for accelerator metrics.

LGTM

thanks, let's plan to tag cadvisor and bump in k/k early in the 1.27 cycle

Sounds good, will do!
