Use non-blocking channel send for UpdateWebhookChan (#4204) 
If the channel send is blocked then there is already an
update queued, and there is no point waiting to queue
another one.

In profiling, the channel send in monitor.go has been
seen to "leak" goroutines as the channel is not being
read from fast enough, but the root cause is not known.
