Proxilate breaks on Node 9+ due to failing timeouts

[ohookins]

Probably related to this: http-party/node-http-proxy#1455

setTimeout in Node 9+ no longer works if the socket is not yet connected. This breaks at least the test suite of Proxilate and also behaviour. Setting the socket timeout option isn't yet working (I believe) due to limitations in http-proxy.

Worth keeping an eye on any workarounds/fixes in http-proxy as it will need to be updated here. There are also numerous out of date dependencies worth taking a look at.
