Is your feature request related to a problem? Please describe.
When multiple instances of application insights are running a race condition is there to inject the traceId on the request sent to the backend.

Describe the solution you'd like
I would expect a way to discard the event from an instance point of view, like we have the dependencyListers and dependencyInitializers

Describe alternatives you've considered
An alternative is to send telemetry manually, so the correct trace-id can be propagated
