Subject: [PATCH] Configurable WiFiClientSecure connect timeout, better default
 value (#4027)

* WiFiClientSecure: use _timeout setting when connecting

This timeout value can be customized via a call to setTimeout function.

Closes https://github.com/esp8266/Arduino/issues/3944.

* WiFiClientSecure: increase default connection timeout to 15 sec
