Issue Description: 

Currently our synchronizer logic runs on a simple scheduled loop. This provides the Control Plane with a periodic update of statuses from the data plane(s). 

A downside with this current implementation is that statuses are only updated when the loop executes. We can improve the responsiveness with the synchronization logic watching for updates to ManagedBridge/ManagedProcessor resources via the K8S API and sending back status updates when they happen.

Acceptance Criteria: 

• Further improve the responsiveness of the synchronization logic by watching for updates to the resource
• The synchronizer should not make any changes to the K8S resources when receiving events. It should simply send the updated status to the Control Plane.
