[receiver/k8sevents] Allow excluding namespaces

Is your feature request related to a problem? Please describe.

In many scenarios I am not interested in events in. certain namespaces 8e.g. istio, kyma, kube-system). However, I would like to per default monitor all other namespaces, as there are users who can freely create namespaces on the cluster that should automatucally be monitored.

Describe the solution you'd like

In addition to allow namespaces = [xxx], it would be helpful to also have exclude_namespaces = [xxx], or even better a regex based approach.

Describe alternatives you've considered

Sounds like a valid request to me.

In the meanwhile, it looks like the namespace is added as a log attribute. Since this is the case, you can use the filter processor to drop all logs from the namespaces that you want to exclude. Look at the alternative config options for logs to see how this could be done.

I'll remove needs triage for now, but the code owners may decide to simply rely on the filter processor instead of implementing this in the receiver. I'll defer to their judgement.

This is a good idea. Also likely impacted by #25161
