Add support for power management tools (tlp, tuned, power-profiles-daemon)

[lehmanju]

To save power on bare metal hardware, it would be beneficial to support power management tools such as tlp, tuned, and power-profiles-daemon.

• tuned is very capable but requires Python and several other dependencies. tuned package
• tlp has fewer dependencies but still offers configuration options. tlp package
• power-profiles-daemon is mainly used in graphical systems and requires minimal configuration.

I already started developing an extension for tuned. However, since it needs python at runtime, how do I add it to the final image? Just copy files from alpine or build it from source? I couldn't find an example extension that does this.
