Emit K8S events to the postgresql CR as feedback to the requestor / user (#896)

Browse Source 
* Add EventsGetter to KubeClient to enable to sending K8S events

* Add eventRecorder to the controller, initialize it and hand it down to cluster via its constructor to enable it to emit events this way

* Add first set of events which then go to the postgresql custom resource the user interacts with to provide some feedback

* Add right to "create" events to operator cluster role

* Adapt cluster tests to new function sigurature with eventRecord (via NewFakeRecorder)

* Get a proper reference before sending events to a resource
