Modified installer produces a k3s-server and k3s-agent systemd
service, with env files located in /etc/rancher/k3s.
The k3s-server service may be started without modification but
k3s-agent requires a token and url modification to the
/etc/rancher/k3s/k3s-agent.env file for functionality.
The k3s-server service will conflict with the k3s-agent service,
so both may not be started at the same time.
Creates ./package/rpm/ repo dir for rpm specific resources and
relocates k3s.spec.
