Hyper-V: detach_interface raises NotImplementedError during neutron event

[Claudiu Belu]

Neutron events have been added to nova. If the event "network-vif-unplugged" is received, the nova compute manager will proceed to call the compute driver's detach_interface method. The mentioned method is not implemented in the HyperVDriver, causing errors. See log.

    Hyper-V: Implements attach_interface and detach_interface method

    Neutron events have been added to nova. If the event
    "network-vif-unplugged" is received, the nova compute manager
    will proceed to call the compute driver's detach_interface method.
    The mentioned method is not implemented in the HyperVDriver,
    causing errors.

    On Windows Hyper-V / Server Threshold (kernel version 10.0), vNICs
    can be attached / detached while the VM are running, if the VM
    is generation 2.

    Adds attach_interface and detach_interface method implementations.
