HS 2.0: Terms and Conditions testing feature in authentication server

Allow hostapd RADIUS authentication server with SQLite EAP user DB to be
used for testing Terms and Conditions functionality. This could be used
for the HO AAA part of functionality (merging HO AAA and SP AAA into a
single component to avoid separate RADIUS proxy in testing setup).

A T&C server with HTTPS processing is needed to allow this to be used
for full over-the-air testing. This commit adds sufficient functionality
to allow hwsim test cases to cover the RADIUS server part.
