[Feature] Add tuned support

[francoism90]

Thanks for creating this image! :)

Would it be possible to add tuned (maybe by default in disabled state)?

The reason is that I use this image on my NAS, but in the night I'm not doing anything useful, and switch to powersaver. It also offers an atomic preset package, which also has profiles for CoreOS. It's weird it isn't installed by default.

For the record, these are the overlayed packages I used on my CoreOS bare-metal install (they have more profile targets):

tuned
tuned-profiles-atomic
tuned-profiles-cpu-partitioning
tuned-utils
tuned-utils-systemtap

The reason for asking this as a request, is that you cannot control this in a toolbox. :)

I think this seems like a reasonable add to the ucore and ucore-hci images, though I would prefer to exclude it from ucore-minimal.

@johnmmcgee @m2Giles do you agree?

@francoism90 would you be interested in creating a PR for this?

I see no reason to not have this. It is a reasonable request and makes sense for some of the use cases that users have showcased in the discord chat.

I second your exclusion from ucore-minimal

@bsherman If you could point me in right direction where to add it, I'll make a PR. :)

[m2Giles]

Would agree as well. No reason not to add for the more featured ones.

I also believe Python dependencies are also already pulled in so this is not a major addition.

Packages for ucore are in a ucore section of the packages.json file. And install-ucore.sh is where you'd need to disable the service.

Give it a shot if interested.
