OpenContrail CNI Plugin

This plugin provides overlay networking for CNI based infrastructures.
It requires a working OpenContrail control plane and a host (aka Compute Node)
with vrouter-agent and vrouter kernel module installed.
The plugin has an IPAM and the plugin part. For now both must run on the Compute
node.
The IPAM plugin runs as a daemon in the background and is responsible for creating
new virtual networks in case it doesn't exist and for assigning IP addresses and
gateway information.
The opencontrail plugin is an executable which creates virtual machine and virtual
machine interface objects in the OpenContrail configuration database.
It retrieves virtual network and ip instance information from the IPAM plugin.
The virtual machine interface is referenced to the virtual machine and the
ip instance to the virtual network and virtual machine interface.
