Comment 4 for bug 1978422

Note that the warning message from the schema check is triggered by both the "lock-passwd" key and the representation of users_groups.user groups key as an array of strings rather than a single string with comma separated group names. I need to change both of those in the json file to make it accept the way that Ubuntu subiquity installer wrote the cloud config.
