- `region_kms_key_ids` (map of strings) - a map of regions to copy the ami to,
along with the custom kms key id to use for encryption for that region.
Keys must match the regions provided in `ami_regions`. If you just want to
encrypt using a default ID, you can stick with `kms_key_id` and `ami_regions`.
If you want a region to be encrypted with that region's default key ID, you can
use an empty string `""` instead of a key id in this map. (e.g. `"us-east-1": ""`)
However, you cannot use default key IDs if you are using this in conjunction with
`snapshot_users` -- in that situation you must use custom keys.
- `run_tags` (object of key/value strings) - Tags to apply to the instance
that is *launched* to create the AMI. These tags are *not* applied to the
resulting AMI unless they're duplicated in `tags`. This is a
