revert: "fix: allow multiple configs listed in KUBECONFIG (#779)"

[adietish]

reverts #779, commit d5972d2.

We merged #779 because things compiled and ran nicely. But then, when implementing the means to compile against IC-2024.2 plugin verifier started to complain (see #801) because it didnt see the modified kubernetes-client classes that existed in the plugin, that were shadowing the ones in the client-jar.

I tried the following without success:

• moved the classes src/main/java -> src/main/kotlin (verifier still complained)
• renamed the package with the shadowing classes (invovles copying even more classes, changing classes in the plugin)
• masked the calls to new method that dont exist in the client-jar using reflection (requires changing classes in the plugin)

When trying reflection we decided to abandon the stop gap solution and wait for the release of the kubernetes-client 7.0.0 which should include the required changes.

Approved, let's hope this will un-block #801 and let's also wait for kubeclient 7.0.0 to be out
