Need a way to stop Send Event Consumer

Right now Send Event Consumer just takes messages off of Event Grid and does it's delay and puts it right back on the Event Grid. If we just stop the function app for Send Event Consumer if it starts back up before Event Grid "dead-letters" those messages they will get sent out.

As of now there isn't a way to clear an event grid subscription.

Start by locating the Send Event Consumer function app and its Event Grid subscription configuration. Review how messages are delayed and returned to Event Grid, then define the supported stopping or clearing behavior. Done should mean the consumer can be stopped without previously received messages being sent again unexpectedly.
