WIP: decrease partition sizes in kickstarts

[vojtapolasek]

This is work in progress. We need to fit default kickstart installation into 20 gb so that we can test it and be efficient with resources.

Skipping CI for Draft Pull Request.
If you want CI signal for your change, please convert it to an actual PR.
You can still manually trigger a test run with /test all

Please try decreasing the size of / instead.

Look at the partitions: Everything big has been moved away from /:

• /usr has its own partition
• /var has its own partition
• /var/log has its own partition
• /home is also separate

There is nothing left for /, it is basically empty. It should not have a static 3 GB allocated, I'd set it to static 1GB at most, with --grow.

I'm trying that in #14520.

Seems I couldn't push to @vojtapolasek fork.

Should be superseded by #14520.
