Bob Kukura c9b0f1abaa Support for the ml2 quantum plugin. ...

Support is added for configuring devstack to use quantum's Modular L2
plugin, ml2. See https://review.openstack.org/#/c/20105/ and the
blueprint for details. Either the openvswitch or linuxbridge L2 agent
can be used with the ml2 plugin (or both in combination on different
nodes). Code configurating devstack for these L2 agents has been moved
into separate files so it can be shared between ml2 and the existing
monolithic plugins.

To use ml2 in devstack, set Q_PLUGIN=ml2 in localrc. By default it
will use the openvswitch L2 agent. To use ml2 with the linuxbridge
agent, also set Q_AGENT=linuxbridge in localrc. The local, flat, and
vlan network types are supported with either agent. Support for
openvswitch's gre network type is not yet implemented in ml2.

Note that ml2 does not yet return a useful value for binding:vif_type,
so nova's GenricVIFDriver cannot currently be used. If using the
linuxbridge agent, work around this by setting
NOVA_VIF_DRIVER=nova.virt.libvirt.vif.LinuxBridgeVIFDriver in localrc.
