Currently we don't expose many options in the class DynamoDBOptions. We have "endpoint" which is only useful for connecting to a local test endpoint, but the option that would be used much more in practice is "region" where you would choose which AWS region to connect to. This task is to implement "Region" as an option in this class, as well as to investigate if there are other meaningful options to add to this class (knowing that this is what defines the connection parameters to all commandline tools).
