This new synthetic field is linked to a "QosPolicyFloatingIPBinding"
register. This binding register will bind a QoS policy and a
floating IP.
Now is possible to provide this field in the create/update input
parameters. If provided, the "FloatingIP" OVO will create/delete the
"QosPolicyFloatingIPBinding" register.
The OVO takes this parameter from the DB object. When the DB object
is retrieved, the QoS policy binding register is retrieved too due
to a backref link in the "QosFIPPolicyBinding" DB model to the
"FloatingIP" DB model.
