Fix for container .env file and small updates

Fix for container .env file and small updates

Since runrapid.py is now supporting more than 1 dataplane interface, we
need to use a port index in the rapid.env file for the dataplane ports.
In k8sdeployment.py, we only support 1 dataplane port, but we are
writing dp_ip1 and dp_mac1 in the environment file. The copyright dates
are also updated. Some references to VM have also been changed to instance.
