> Why is this change needed?

Before, there were two separate mechanisms - S3 objects got encrypted using a KMS,
if present, and the IAM / configuration data got encrypted with the root credentials.
Now, MinIO encrypts IAM / configuration and S3 objects with a KMS, if present. This
change unified the key-management aspect within MinIO.
