Add support for Ubuntu 24.04

[Bischoff]

What does this PR change?

This PR adds support for Ubuntu 24.04. Part of https://github.com/SUSE/spacewalk/issues/23851.

Follow-up of #1691 from @nodeg (Dominik being absent).

For technical reasons it replaces packages: with runcmd: for cloud-init like in @srbarrios 's PR #1705.

TODO

• wait for all Devel repos being available in OBS/IBS
• DO NOT wait for SCC enabling products, as Ubuntu 24.04 is not published yet

Looks good to me, I didn't check the urls and not sure if there's anything missing from another place but I don't think so.

First tests show that the minion has its interface down:

2: ens3: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
    link/ether aa:b2:93:01:01:4b brd ff:ff:ff:ff:ff:ff
    altname enp0s3

Probably again a cloud-init pain... Will try to fix it tomorrow.

After a lot of fixes, it seems to work.
