Wifi diagnostic app to enable debug and provide information

This is the first checkin on the wifi diagnostic app. Right now,
it supports using the WifiManager API, shows the configuration details
and provides status on the supplicant, network and wifi state along with
some additional details.

More to come:
- add more API and status on any additional fields
- provide a way to show some logs
