Add plugin config, systemd config, netplan config, software installation via ssh, and a quick HowTo for setting up a double-nat test gateway. Fix a minor doc bug which caused a complaint on vpp-dev@lists.fd.io: /etc/vpp/startup.conf -> /setup.gate, but the vpp configuration file wasn't explicitly tagged with the name /setup.gate.
