Replace event related code with Kube's EventRecorder

[linki]

Replaces the feature of exporting events from #105 to use Kubernetes' EventRecorder.

With this:

• exporting events is enabled by default and cannot be turned off
• events are attached to the Pod being killed as opposed to the namespace it's in
  • kubectl get events can be used to show the events, see line four below.

$ kubectl get events

@djboris9 @ghouscht @se7enack This changes #105 to enable exporting events by default and changes where they are attached to (the source). Let me know what you think about it.
