Add plan command node-token command

Description

k3sup plan is used to read in a list of devices and to generate an installation script for a HA cluster.
k3sup node-token is used by scripts generated by k3sup plan to avoid too many SSH connections by each joining node back to the server.
SSH connection code is moved into a common helper method, instead of getting repeated

How Has This Been Tested?

Usage:

devices.json

[{
        "hostname": "node-1",
        "ip": "192.168.1.128"
}]

Command:

k3sup plan \
  --tls-san $SAN \
  --servers=3 \
  --user ubuntu \
  --background=true/false > bootstrap.sh

chmod +x bootstrap.sh

./bootstrap.sh
