nova-scheduler crashes with the cisco Quantum scheduler

[Mathieu Rohon]

when the nova scheduler is launched with the option :

--scheduler_driver=quantum.plugins.cisco.nova.quantum_port_aware_scheduler.QuantumPortAwareScheduler

it crashes when the scheduler gets an update_capabilities message from amqp :

    Calling Super method from QuantumPortAwareScheduler.__init__

    the quantum.plugins.cisco.nova.quantum_port_aware_scheduler.QuantumPortAwareScheduler class wasn't calling its superclass __init__.
    the host_manager attribute of driver.Scheduler class wasn't initialized, and the scheduler was crashing when it was receiving a host message via amqp.

    Fixes bug 994652
