Adds tcp_keepalive and tcp_keepidle config options

Currently the wsgi server will not close connections once requests
complete and will not enable keepalive on it's wsgi sockets. This can
be a problem for those who need to align the server keepalive with
load balancer timeouts without modifying system keepalive settings.

To remedy this we add new config options tcp_keepalive and
tcp_keepidle which are disabled by default to remain backwards
compatible.
