Clients are now authorized by client= argument in URL, schema and client lib is updated accordingly. Method authentication defined in "expose" decorator. Added Client container class for deterministic logging. Schema update to consistent InnoDB and utf8mb4 everywhere.

Now auth/auth actually works. Now uses services on many places, where clients was used (and didn't work)

Fixed for now: /opt/warden_server_3/warden_server.py:427: Warning: Field 'request' doesn't have a default value
