Introduce Http2DirectAttribute
Now that we have a proper ALPN/NPN + Protocol Upgrade, we can also
add H2Direct - this can be useful for our users that have to work
with either Secure Transport or a TLS implementation not supporting
ALPN/NPN and with 'h2direct' servers in case they have prior knowledge
of HTTP/2 support. The difference with RFC 7540 is the fact we also
allow this 'direct' in case of 'https' scheme (it appears existing
HTTP/2 server implementations support such mode too).
[ChangeLog][QtNetwork] Add Http2DirectAttribute to enable 'direct' HTTP/2
protocol without ALPN/NPN and without protocol upgrade negotiations.
Task-number: QTBUG-61397
Change-Id: I0499d33ec45dede765890059fd9542dab236bd5d
