Add support for controlling what data is returned from queries #186
Description
Add command-line options which allows the user to specify what queries should return:
--include_values/--no-include-values- Should the vector values be returned from the database? (For some databases this requires additional work to fetch the actual vector values)--include_metadata/--no-include-metadata- Should the record metadata be returned from the database? (For some databases this requires additional work to fetch the metadata)
