Sahid Orentino Ferdjaoui ff747792b8 libvirt: slow live-migration to ensure network is ready 
In Neutron, commit b7c303ee0a16a05c1fdb476dc7f4c7ca623a3f58 introduced
events sent during a live migration when the VIFs are plugged on
destination node.

The Linux bridge agent mechanism driver is detecting new networks on
the destination host only when the TAP devices are created, and these
tap devices are only created when libvirt starts the migration. As a
result, we must actually start the migration and then slow it as we
wait for the neutron events.

This change ensures we wait for these events.

Depends-On: Icb039ae2d465e3822ab07ae4f9bc405c1362afba

Conflicts:
        nova/tests/unit/virt/libvirt/test_driver.py
        nova/virt/libvirt/driver.py

NOTE(lyarwood): The driver.py conflict is due to additional QEMU and
LIBVIRT version constants being present in Queens. The test_driver.py
conflict being the result of our need to assert byte strings in Pike as
also seen by I9b545ca8aa6dd7b41ddea2d333190c9fbed19bc1 and resolved by
I85cd9a903fba310b5ae7bedeed118ca4ea98dff6 in Queens.

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:

Developers
