Make kubeobject utils more generic

[0sewa0]

Description

K8S-9483

Basic idea is to have the same interface for interacting with the kube-api, as we have multiple ways of doing it.

Changes: (the commits are semi-nicely structured)

• Stopped using the Modifier/Builder interface in the kubeobjects, as it was overkill and made a simpler one
• Replaced the Query struct with a generic implementation that is reusable for every client.Object
• Updated all previous Query objects usages
• If I touched a file, I updated the imports accordingly
• Replaced some obvious copy-paste code:
  • 806f5ea
  • 113553b
  • 7eac4b6

Sidenote:

• The generic Query struct evolved as I replaced the old utils, so it can be used for all current usecases
• There are still soooooo much to fix, but this PR is already too big to nicely review, so I will create follow-ups.
  • Example:
    • The folder structure of kubeobjects could use some love
    • I didn't replace all the "old utils"

How can this be tested?

No change in behaviour

convert it back to draft, forgot about the owner-reference 😅

Tested with simple cloudnative deployment, everything alright 👍

works well in my cluster, especially with both EC setups.
