> Add support for "authoritative mode" for DynamoDBMetadataStore.
> The missing feature is to persist the bit set in {{DirListingMetadata.isAuthoritative}}.
> This topic has been super confusing for folks so I will also file a documentation Jira to explain the design better.
> We may want to also rename the DirListingMetadata.isAuthoritative field to .isFullListing to eliminate the multiple uses and meanings of the word "authoritative".
