Blaze Http2 Support Is Bugged

See original GitHub issue

Opening per a conversation w/ @ChristopherDavenport

Created a server like so:

http2Server = BlazeServerBuilder[IO](ExecutionContext.global)
          .bindHttp(serviceConfig.http2Port, "0.0.0.0")
          .withHttpApp(app)
          .withSslContext(context)
          .enableHttp2(true)
          .resource

When sent Http2 requests, it seems to be going into the Http1 stages:

Yep, I saw that. My use-case runs on JDK11 today so we are good there 😄
