Automated ng-cdi intent demo stuff

Running

1. Start everything up:docker-compose up
2. Connect to the onos cli: ssh -o StrictHostKeyChecking=no -l onos -p 8101 localhost
3. !!important!!: In the onos cli, run: imr:startmon 187 org.onosproject.ifwd

To shut down

1. Send C-c or docker-compose down
2. If you still have cores spinning after stopping, run sudo mn -c on the host.

Make sure you have

1. openvswitch installed on the host (the kernel module is needed), you probably want mininet installed too just in case.
2. if something complains about a hostname not being found, make sure the host's /etc/hosts has 127.0.0.1 localhost
