Subject: [PATCH] Add setKeepAlive for net.socket

* Prevent `Error: read ECONNRESET` when using net.socket by using
setKeepAlive when connecting.
* Use an `initialDelay` of 60 seconds.

Net -> socket.setKeepAlive:
https://nodejs.org/api/net.html#net_socket_setkeepalive_enable_initialdelay

Closes #38, #41
