Many APIs does not do schema validation for the inputs.

[[e-mail]]

We had removed the input validation in API layer, so we depends on the wsgi layer to do the validation.
But now we can find many handlers does not do the validation at all.

A few examples in handlers/guest.py:

guest_couple_uncouple_nic
guest_create_network_interface
guest_create_nic
...
