Any test validating existence of new event timeline in query profile?

Unrelated question: Do you know if updating table property will raise HMS 
event? If yes, how CatalogD deal with it? Asking for

Who is waiting? Maybe tell us something about this flag in commit message?

Please add gauge / metric on how much WaitForHmsEvent RPC is currently hung up 
waiting.

ID");

This pattern if timeline != nullptr check followed by timeline->MarkEvent() 
repeated in multiple places.
Maybe worth to make an inline function for it.

Is this strict for DEVELOPMENT / testing, or do you envision this to become 
ADVANCED? Need documentation?

Except for EventProcessorUtils.wait_for_event_processing_impl removal in favor 
of EVENT_SYNC_QUERY_OPTIONS, other changes in this method is just indentation 
adjustment, correct?
