Extended Nailgun data driver to parse new ks_meta keys.
Extended Ubuntu cloud-init config template to create a non-root
account. Root login is being disabled, however, this setting
will only be effective until osnailyfacter::ssh puppet class
will have been evaluated during deployment as it overrides
sshd_config values. This means, that PermitRootLogin should be
managed by library as well.
