  Log:
    Add ipaddr optional parameter to Net::HTTP#start
    
    to replace the address for TCP/IP connection [Feature #5180]
    
    There're 3 layers of hostname:
    * host address for TCP/IP
    * TLS server name
    * HTTP Host header value
    To test DNS round robin or check server certificate from server local,
    people sometimes want to connect server with given IP address but keep
    TLS server name and HTTP Host header value.
