Fix issue #561 in ZitiConnectionSocketFactory (#562)

* Fixed #557 with the response timeout using the incorrect units
Added convenience constructor to ZitiConnectionSocketFactory for referencing an existing ZitiContext

* Fix #561 by using the InetSocketAddress.createUnresolved to avoid the host lookup delay
