Automate building and publishing cri-tools and kubernetes-cni packages

[xmudrii]

cri-tools and kubernetes-cni were automatically built and published on Google infra. However, as we don't have reproducible build (#3170), this is not an option on OBS. As of now, we can manually build and publish these packages using krel obs stage and krel obs release

While this is good enough for now, we should look into automating build and publish process for these packages. Automation can be based on some promotion workflow similar to images where you define in which project to build and publish these packages via some YAML manifest.

/sig release
/area release-eng
/kind feature
/priority important-longterm

The CNI plugins package is published in isv:kubernetes:core:shared right now. We manually aggregate them into the corresponding release project like this (for v1.30):

osc aggregatepac isv:kubernetes:core:shared/kubernetes-cni.20240110204507 isv:kubernetes:core:stable:v1.30:build
osc release isv:kubernetes:core:stable:v1.30:build/kubernetes-cni.20240110204507
