Add Server Side Apply (SSA) example

[Jasstkn]

Hi! I want to contribute an example with SSA. Could you help me to figure out in which way it should be done?

[guettli]

yes, this would be nice to have.

Is using ApplyPatchType enough, or do I need to use "k8s.io/client-go/applyconfigurations/core/v1"?

I could not find examples for that.

@Jasstkn, looking at your GitHub status, I get it you won't have time for this any time soon 🙈 Am I correct? Unfortunately, my focus has also shifted from Kubernetes controllers to some other things. But I hope to revive this initiative one day.
