Shortening up the default hard-coded 8000 ms timeout, will save energy when module can't reach its update server, especially on battery powered projects, and otherwise provide adaptability to the local wlan. The ESPhttpUpdate object is auto-created by #including ESP8266HTTPUpdate. ESP8266HTTPUpdate also provides a constructor with param httpClientTimeout, but to use it required destroying the auto ESPhttpUpdate object, or creating a secondESPhttpUpdate(timeout) object.
