plugin-nvidia: collect nvml process metrics

[victoryeagle77]

[ DONE ]

• Add process_utilization_metrics function, using the NVML "process_utilization_stats" method.
  Allow to pooling running_compute_processes and running_graphics_processes by process PID and LocalMachine GPU consumers, for the final data feedback.

• The major_utilization metric is now used globally and by PID for graphics and computing processes.
  Used to evaluate frame buffer memory utilization.

• The encoder_utilization metric is now used globally and by PID for graphics and computing processes.

• The decoder_utilization metric is now used globally and by PID for graphics and computing processes.

• The new added metric sm_utilization is used globally and by PID for graphics and computing processes.
  It refers to the percentage of time that the Streaming Multiprocessors (SMs) of a GPU (SM 3D compute utilization).

---

• Add GPU temperature monitoring.

• Refactoring of "nvml.rs" code file in different files in a nvml directory :

  • "device.rs"
  • "features.rs"
  • "metrics.rs"
  • "probe.rs"

• Add unit tests in nvml directory and "lib.rs"

Please rebase on the master branch of upstream. If the upstream remote (alumet-dev/alumet) is named origin in your git config, do:

git fetch origin
git rebase origin/main

Why did you change the plugin-cgroupv2 in a PR about the NVML plugin ?

[TheElectronWill]

The tests need to be removed for now, you can keep them in git stash.

Also, it would be better to make this two separate commits:

1. add the new measurements
2. refactor in separate files

The goal is that it's easier to review because we see what has changed in the probe, in the current situation I just see "old file deleted" and "new files added".

But it's not a big deal this time, think about it next time ^^

[TheElectronWill]

Here are some changes about the documentation. Unlike some other languages, the Rust convention is to write simple sentences that explain what the function does, not to list the parameters or returned result.

[TheElectronWill]

you need to run cargo fmt to format your code

Please separate the work on jetson in another PR
