TrackerEvent NewEvent ()

Create a `TrackerEvent` used to record a latency or error value. Can be moved between threads.

The returned `TrackerEvent` must not outlive the associated `OperationTracker`.

Time measurement starts when this object is created and ends when it goes out of scope.

Use `TrackerEvent::SetStatus` to record the result of the operation.
