tests: Add ap_config_reload_on_sighup_config_id

Browse source 
The test checks that when reloading the configuration with SIGHUP,
stations that are connected to BSSes whose config_id did not change are
not disconnected. It also checks that for the BSSes that have a
different config_id and SSID, the new SSID is applied correctly.
