Review Comment:
Can we also handle this for Drop namespace?

Review Comment:
We should wrap it with `withReference`, it handles using new client when
ref@hash is used by catalog (instead of latest hash)

Review Comment:
we should also add a retry like `renameTable()` and `dropTable()`, only for
the `commitTable()` retry is not needed as Iceberg has a built in retry for it
from a transaction.
