As discussed in #1323, there is now sufficient community interest in moving forward with a Rust FlightSQL implementation. Thanks to @avantgardnerio and @wangfenjin we have basic POC level client and server implementations behind the --features=flight-sql-experimental feature flag.

This ticket tracks the work needed to change the feature flag from flight-sql-experimental to flight-sql (aka that we are comfortable saying that the rust client supports FlightSQL)
