Review Comment:
I see your point, but this is not how Iceberg table encryption currently
works. The "old" keys you are referring to (aka those that encrypt snapshot
files) are internal to a table and not part of the KMS managed keyset.
Therefore those will never be part of the `key-management-credentials`.
Right now there's only one key per table in KMS which acts as the topmost
level KEK. The reason I'm referring to KMS keyS (so plural) is to allow future
column-level encryption in this spec.
