    move os_vif.initialize() to nova-compute start

    os_vif.initialize() was previously executed during module load. This
    means it was entirely possible that it was run before things like
    logging were actually set up in the expected way. Move this back into
    execution time instead of load time to ensure that logging is actually
    setup.

    Changes need to be made to tests which make assumptions about os_vif
    objects to manually initialize os_vif when it will be used. os_vif
    objects can't be created until it is initialized, so some delayed
    object creation is also done in test_vif.py.
