tests: Add WPS test with dynamic update

Browse source 
This test first configure hostapd with an initial SSID
('test-wpa2-psk-start'). Then a new SSID is configured
('test-wpa2-psk-new') using SET and RELOAD. Next, a station is
associated using WPS, and the test verifies that the new SSID was served
to the station.
