The sidecar now has a control loop, which watches its ClusterIP
Service for the `cassandra.rook.io/decommissioned` label.
If it finds it, then it decommissions and updates the label to
value "true".

We add a new label to our constants, called
`cassandra.rook.io/decommissioned`. When it is present on a
member's ClusterIP Service with the value "false", it expresses
the intent of the controller to decommission the member. When it is
present with the value "true", it means that decommission has completed.

Implementation of the cassandra sidecar logic.

- Shutting Down / Decommissioning a cassandra instance
- Backups
- Restores
