    mark vif_driver as deprecated and log warning

    Several classes were dropped from nova.virt.libvirt.vif from havana ->
    icehouse, leading to invalid configurations if one of these classes was
    used in the libvirt_vif_driver setting in nova.conf. The error message
    produced by nova-compute in this situation is misleading.

    This patch introduces stubs for all of the classes that were removed.
    These stubs inherit from LibvirtGenericVIFDriver and log a deprecation
    warning in __init__.

    This patch also marks the vif_driver option as deprecated.
