Switching from Ansible Vault to age.
I've changed the `upsd.users` template somewhat in order to handle the
`password` property separately. Now, items in the `nut_users` list
are objects with properties instead of lists of objects with properties.
The latter was done to support repeating options (`actions` and
`instcmds`), but that is more appropriately handled with lists of
values.
This value is encrypted with the following public key:
