> Improve HTTP upgrade connection
> -------------------------------
>                 Key: ARTEMIS-931
>                 URL:
>             Project: ActiveMQ Artemis
>          Issue Type: Bug
>          Components: Broker
>    Affects Versions: 1.5.2
>            Reporter: Jeff Mesnil
>             Fix For: 2.0.0, 1.5.3
> When Artemis connector is configured to use http-upgrade, it will send an HTTP request
to the server to perform the upgrade handshake and wait for response for 30 seconds maximum.
> The code in HttpUpgradeHandler#channelRead0 checks if the received object from the server
is a HttpResponse and check its header.
> However if the received object is not an HttpResponse (e.g. a LastHttpContent if the
web server is suspended and returns a 404 with a text content), the code does not close the
context and does not countdown the latch.
> This results in a 30s block for the client when we already know that the connection will
not be possible.
> Improving code in  HttpUpgradeHandler#channelRead0 will remove this 30s wait time and
ensure a fast dectection from the client so that it can try to connect to another server for
