But <retry/> is in an error stanza.
The flow is like this:
1. Client sends iq to HTTP upload service.
2. Clients quota is exceeded, so HTTP upload service replies with type="error"
including the <retry/> element.
3. What happens now if ejabberd doesn’t know the <retry/> element? Who gets
the error? Does the client receive an error for their upload request, or will
they time out while waiting for their reply?
