    [NO ISSUE][HYR][HTTP] Fix omitted access log on some netty responses
    
    The CLFLogger had assumptions that if a DefaultFullHttpResponse was
    not received, it would receive one or more DefaultHttpContent
    instances followed by a LastHttpContent. In reality, Netty is free to
    return a DefaultHttpContent that also implements LastHttpContent,
    which causes the CLF log entry to never be emitted.
