Add Events for far Remediation Process

[razo7]

To ease the tracking of the remediation process of far custom resource we add events to indicate major milestones (such as fencing, workload deletion, etc.)

1. Adding events (and unit testing)
2. Check whether NoExecute taint was added to signal an event.
3. Only use GetNodeWithName instead of IsNodeNameValid which is no longer needed.
4. Small refactoring to unit tests

May I ask you to wait for #106 before merging this? Many events come from the fence agent execution that is reworked in that PR.
