Midonet to support using 'mm-ctl' for binding ports

[Joe Mills]

Currently Midokura uses its own script (mm-ctl) to bind ports. However, support for using this script was left out of the Nova and Neutron projects purely due to negligence. mm-ctl is the correct way to bind ports but because we have not been doing this, it has caused problems occasionally. This fix is to change Nova to properly set up port bindings to use the "midonet" vif driver when creating a port. Lack of mm-ctl support also causes issues with clients that required upstream vif driver support.

    Add port bindings to ports created in Midonet

    Currently Midokura uses its own script (mm-ctl) to bind ports. However, support
    for using this script is left out of the nova and neutron projects. This causes
    confusion and makes deployments unnecessarily complicated for customers using
    Havana. This fix is to change Neutron to properly set up port bindings to use
    the "midonet" vif driver when creating a port. Corresponding changes will be
    submitted to the devstack and Nova projects.
