Subject: HTTP/2 - make protocol settings configurable
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

1. Recently we have updated our receive window size to a larger value.
Unfortunately, this also results in auto-test pumping through
more data, which probably takes more time on CI.
At the moment we do not have any public API on QNAM's level to
customize HTTP/2 parameters (aka 5.10/FF and so on). So we use the fact
that QNAM is QObject and we can set a property on it. This property
is our Http2::ProtocolParameters object that allows us to configure:
- HPACK parameters (in 5.10 - noop)
- session receive window size
- different SETTINGS as described by RFC 7540, 6.5.2.

2. Undocumented environment variable to set ENABLE_PUSH is not needed
anymore.
3. In 5.11 Http2::ProtocolParameter will become a public API
and we'll introduce a new setter in QNAM.
