A registered image must have two properties set:
* username - a name of the default cloud-init user.
* tags - certain tags mark image to be suitable for certain plugins.
* tags - certain tags mark image to be suitable for certain plugins. The tags
depend on the plugin used, you can find required tags in the plugin's
documentations.

plugin used. You can find both in the respective plugin's documentation.
