[PATCH v2 0/2] Add cpupower idle-state functionality

["John B. Wyatt IV" <jwyatt@redhat.com>]

This patch series adds idle-state functionality to control cpu power
usage and to test idle states.

The number of cpus was needed in the cpupower file; I extracted out the
previously local to tuna-cli.py functionality to a separate file so the
cpu code can be used in any file in Tuna and reduce duplications. The
nics code was similar so it was also extracted to reduce the number of
global variables.

Sincerely,
John Wyatt

Changes v1 -> v2:
- Numerous improvements suggested by Crystal Wood including message
  text, output, error handling, moving a function to utils.py and
  structure of the code.
- Fixed a libcpupower bindings detection error that did not show on
  my local machine but did on a fresh install of Fedora GNOME 40
  reported by John Kacur.
