Filter by OwnerReference's Kind

[qlikcoe]

This PR adds new flag --kinds.
It allows us to include/exclude specific Kinds of pods or, to be more specific, filter by OwnerReference's Kind.

So, for example, you can exclude any pods created by any DaemonSet by using the following flag:

--kinds="!DaemonSet"

@qlikcoe That's awesome! 😀

@qlikcoe Awesome stuff 👍 I removed a piece of code in the kinds filter that is obsolete, I think. Tests are still passing.

Let me know if you disagree. Otherwise I'll merge this.

A big thank you 🥳 and sorry for the delay!

[qlikcoe]

@linki looks good!

[linki]

@qlikcoe Thanks again!
