* Added TCP Keep-alive support by passing use the socket_keepalive=True
option. Finer grain control can be achieved using the
socket_keepalive_options option which expects a dictionary with any of
the keys (socket.TCP_KEEPIDLE, socket.TCP_KEEPCNT, socket.TCP_KEEPINTVL)
and integers for values. Thanks Yossi Gottlieb.
TCP_KEEPDILE 设置连接上如果没有数据发送的话，多久后发送keepalive探测分组，单位是秒
TCP_KEEPINTVL 前后两次探测之间的时间间隔，单位是秒
TCP_KEEPCNT 关闭一个非活跃连接之前的最大重试次数
