This metric tracks when backup replicas perform failover to fulfill requests that the primary replica failed to handle. It will be used for alerting when primary instances are not working correctly. Co-Authored-By: Tejas Badadare <[email protected]>

Summary
Add a counter than increments when a Fortuna replica acting as backup attempts to fulfill a request. This indicates that the primary replica failed to fulfill the request in time. We will add an alert based on increase of this metric to let us know the primary isn't working correctly.
How has this been tested?
