apacheGH-37795: [Java][FlightSQL] Add mock FlightSqlProducer and tests (
apache#37837) ### Rationale for this change Clarify how to write a FlightSqlProducer with examples and helper classes. This is more inline with what's available to help developers write a FlightProducer. ### What changes are included in this PR? Add helper classes for creating a No-op Flight SQL producer and a partially implemented FlightSqlProducer that can process metadata requests. Add a mock flight producer and tests for it based on the new FlightSqlProducer partial implementations. Clean-up missed closes of FlightStreams in TestFlightSql. ### Are these changes tested? Yes. ### Are there any user-facing changes? No. * Closes: apache#37795 Authored-by: James Duong <duong.james@gmail.com> Signed-off-by: David Li <li.davidm96@gmail.com>
