[FlightSQL] Allow returning column remarks in FlightSQL's `CommandGetTables`

[mateuszrzeszutek]

Describe the enhancement requested

Hey,

Currently when you call CommandGetTables with include_schema = true the message you get in return contains schemas, and each field on these schemas may contain couple of different metadata properties: type name, scale, precision, etc. What's missing is column remarks/comment/description -- for example, when you use JDBC to retrieve columns for particular table(s) the API allows the drivers/databases to return remarks in the REMARKS column of the result set.

Would it be possible to add a ARROW:FLIGHT:SQL:REMARKS metadata property to the CommandGetTables contract to allow retrieving column descriptions?
