Changing public key with public certificate URL on NS_UA_WS
Added client certificate auth in AS frontend

Simplified certificate check using only the fingerprint
Protect AS to non-client certificate connections
Updated tests & scripts to the new certificate way of auth
Check if no cert found in the DB in the callback method
Simplified the way the notification is checked
More clear way to get the kind of protocol to recover the client certificate
Removed the non-ssl option to AS frontend since with the new auth method SSL is always required
