Allow the client-facing server to GREASE the extension. #481

Closed chris-wood closed 3 years ago

This assumes the formulation where, on ECH reject, the server is the client-facing server. In other words, backend servers will never get a CH without ECH having been accepted, so GREASE doesn't apply there.
