Nr 337529 infra agent flaky test

[rahulreddy15]

Timeout was increased to 500 * time.Millisecond allow enough time to set things up correctly.
The flakiness was due to the test expecting this specific error http2.ErrUnexepectedResponseCode.Error() but instead might get "context deadline exceeded" as the error sometimes.
By increasing timeout, there is more time for the right response to be received from the server.

Another way would be to expect that the server might timeout sometimes and check for "context deadline exceeded." .
