[ovs-dev] The “overlay” mode issue while setting up OVS with DPDK

I have a 2 node vagrant scripts in a private repo that I use to test the
Docker integration with OVN here:
https://github.com/shettyg/ovn-docker/tree/master/vagrant_overlay

I tested this again today with OVS 2.9.2 and the latest docker and it
passes my sanity tests. If you have a mac and virtualbox, it should
probably be as simple as "vagrant up". Otherwise, you can look
at consul-server.sh, consul-client.sh, install-docker.sh and install-ovn.sh
on a ubuntu to reproduce the environment.
