Bug 1932308 - Do not send PRIORITY_UPDATE H2 frames a=pascalc

Browse source 
As far as I can tell, this problem occurs regardless of what is
in the PRIORITY_UPDATE frames. I suspect the connection gets closed by
the server because it's receiving a lot of HTTP/2 frames it does not
understand, and treats these as a DoS attack.

I've also tried to convince Chrome to generate a PRIORITY_UPDATE frame
but I was unsuccessful.

My suggestion is to disable sending PRIORITY_UPDATE for now.
