Remove the declaration of thrown runtime exceptions across codebase.

[rohanKanojia]

Description

There are a few places in our codebase where we have throws XYZException in our methods, even if XYZException is a RuntimeException. We should refactor these places to remove these throw occurrences. Consider this place:
https://github.com/eclipse/jkube/blob/90439cb98fef038e8c991825d2a90ce414787fb6/jkube-kit/build/service/docker/src/main/java/org/eclipse/jkube/kit/build/service/docker/access/ContainerHostConfig.java#L95-L98

This should actually look like this:

public ContainerHostConfig extraHosts(List<String> extraHosts) { 
     // ...
}

You can find out these places via a simple grep command:

jkube : $ git grep -in "throws KubernetesClientException\|throws IllegalArgumentException\|throws NumberFormatException\|throws ExternalConfigHandlerException"
