WiFiClient.setConnectionTimeout added

[JAndrassy]

the connection timeout in WiFi101 library was hardcoded and is unreasonable long 20 seconds.
the Ethernet library has setConnectionTimeout.
this PR adds setConnectionTimeout to WiFiClient.
default timeout is still 20 seconds but can be set with -DWIFI101_CLIENT_CONNECTION_TIMEOUT
