// TestGracefulShutdownForActiveHTTP2Streams checks if graceful shut down of HTTP2 server works.
// It expects that all active connections will be finished (without any errors) before the server exits.
//
// The test sends 25 requests to the target server in parallel. Each request is held by the target server for 60s.
// As soon as the target server receives the last request the test calls backendServer.Config.Shutdown which gracefully shuts down the server without interrupting any active connections.
//
// See more at: https://github.com/golang/go/issues/39776
//
// Note this test will fail on upstream golang 1.15
