Three new network quality client hints

Support for the “rtt”, “downlink”, and “ect” client hint values and HTTP request headers have been added to Chrome to convey Chrome’s network connection speed to servers. These network quality hints provide the same values as existing Network Information APIs navigator.connection.rtt, navigator.connection.downlink, and navigator.connection.effectiveType.
