Goal

Today the Administrating Satellite guide has a section on Tuning Satellite server with predefined profiles (6.18). This same chapter is also included in the installation guide. In the docs this comes from the same asciidoc files.

In the interest of time a copy of the current concept is the least risky. It works well enough that we don't need to change it now.

In the new implementation there isn't a custom-hiera.yaml file anymore so this can be dropped from the documentation. It also needs an updated description of where to find the various sizes.

Acceptance criteria

• foremanctl accepts --tuning PROFILE with the same profiles as today
• This is tested
• The documentation is updated.

Open questions

• Since the scenarios are gone, the tuning will also apply to the non-Satellite cases (like Capsules). Will this be a problem?

Implementation notes

• Today tuning is implemented via installer hooks: hooks/boot/13-tuning.rb to introduce the CLI option and hooks/pre_commit/13-tuning.rb to actually apply the tuning.
