Added CONNECT method rejection. No valid CONNECT requests are expected to appear within nginx, since it is not a forward proxy. Further, request line parsing will reject proper CONNECT requests anyway, since we don't allow authority-form of request-target. On the other hand, RFC 7230 specifies separate message length rules for CONNECT which we don't support, so make sure to always reject CONNECTs to avoid potential abuse.
