Remove k8s client spring integration dependency

this is an easy fix that took almost a day to figure out. :) While working on a different thing (add support for selective namespaces in discovery k8s-client), I wrote some integration tests that were constantly failing. After investigation, I realized that some beans that we create, for example:

	@Bean
	@ConditionalOnMissingBean
	public SharedInformerFactory sharedInformerFactory(ApiClient client) {
		return new SharedInformerFactory(client);
	}

were never created by us, but were coming from this maven dependency.

We do not require it anymore, since we don't use anything from it (the vast majority of things that we were using were deprecated inside it and we refactored our code in a different PR anyway).

As such, currently, we do not depend on anything from this maven dependency, instead it just clutters our spring context (and breaks some integration tests that I was working on)
