cloud-init: homedir and shell are required when creating new users

[mudler]

Booting with the following cloud-init file fails adding the vagrant user:

#cloud-config

# Add additional users or set the password/ssh keys for root
users:
- name: "root"
  passwd: "ros"
  ssh_authorized_keys:
  - https://raw.githubusercontent.com/hashicorp/vagrant/main/keys/vagrant.pub
- name: "vagrant"
  passwd: "vagrant"
  ssh_authorized_keys:
  - https://raw.githubusercontent.com/hashicorp/vagrant/main/keys/vagrant.pub

Ok, this seems to be a simple cloud-init nuance, it looks like the homedir and shell field don't have defaults, so they are mandatory when creating new users.

This indeed works:

#cloud-config

# Add additional users or set the password/ssh keys for root
users:
- name: "root"
  passwd: "ros"
- name: "vagrant"
  passwd: "vagrant"
  shell: "/bin/bash"
  homedir: "/run/vagrant"

I've been testing in openstack with the https://github.com/rancher-sandbox/os2/tree/fixups/cloud-init branch

It actually needs a bump in elemental-cli 🥲
