Red-X uses the EC2 Parameter Store to load its configuration. Let's make sure you
have all of the correct parameters created in the right paths and the right ones
are encrypted.

Note: This script assumes you have already deployed the function and makes use of
a KMS key it creates. If you don't wish to use the red-x KMS key, please update
the KeyId in `configure.py` before running this.
