HS 2.0: CoA-Request from Terms and Conditions server

This extends the terms.php implementation of Hotspot 2.0 Terms and
Conditions server to allow it to interact with hostapd(AS) to clear the
filtering rules from the AP. After requesting hostapd to send out the
CoA-Request, terms.php waits for up to 10 seconds to see whether the
current_sessions table gets an update to indicate that filtering has
been successfully disabled.
