Clarify that netinfo rtt API returns RTT at the application layer #67

The spec currently says:" ...based on recently observed application-layer RTT measurements across recently active connections...". Some developers have interpreted this to mean that the returned RTT reflects the transport layer RTT, and is computed using the application layer RTT. This is an incorrect interpretation.

We should update the spec to make it clearer that this is measured at application layer, and remove any room for confusion.

The time between when a request is sent, which may require new connection setup or not, and the first byte of the response is received

The above is what made this perfectly clear to me if it helps :)
