The entire encryption layer is dependent on the fact that KMS should be configured for S3 encryption to work properly and we only support passing the headers as is to the backend for encryption only if KMS is configured. Make sure that this predictability is maintained, currently the code was allowing encryption to go through and fail at later to indicate that KMS was not configured. We should simply reply "NotImplemented" if KMS is not configured, this allows clients to simply proceed with their tests.
