Yamllint configuration needs improvements

[tuminoid]

Our yamllint config is quite simple and needs improvements. For example, we want to enforce yaml to be linted in k8s way, meaning lists are not indented.

Study the yamllint tool, and its options and decide what is the acceptable level of enforcement. Make the change here in project-infra (as it is the only repo where it is implemented right now), then add the linter to other repos as well.

Some notes to consider:

• We have manifestlint check in CAPM3/IPAM/IRSO/BMO, which might or might not have options for this too. Check the synergies with that
• yamllint action is out of date by 3 years, not maintained
• the tool under yamllint action is maintained, so changing the action might be needed, or changing workflow to prow job
