Review comment:
Because it is not straightforward to get a consistent glue catalog ID,
unless we always initialize a client to fetch the AWS account and region from
the caller, which creates lots of complications. By doing this, you basically
have one dynamo lock table for one Glue catalog, which is simpler.
