Updating docstring for the audio plugin

Updating the docstring for the audio plugin to include more info and sample usage

Thank you for the PR. Why is this PR exactly the same as https://github.com/redhat-performance/tuned/pull/315 ? I.e., both include docstrings for sysctl and audio plugins. Also, I'd suggest squashing the commits to a bare minimum prior to merge. Finally, I remember having been asked to --signoff by tuned mainainers in the past (see the git log).

Yeah, I made a mistake when pushing the commit. I'll squash the commits next time and check to see why I have the sysctl and audio plugins in the same commit. I apologize for that. Not sure why I'm getting both plugin docstrings in this PR.

@courtneypacheco please squash the commits to one. Use e.g. git rebase -i for it, then force push from the branch git push -f.
