Description

When virtual tables were implemented (CASSANDRA-7622), cqlsh.py was updated to parse virtual keyspace metadata by making queries to the system_virtual_schema table and included a TODO:

# TODO remove after virtual tables are added to connection metadata

Since python driver 3.15.0 (released in August), the driver now parses virtual keyspace metadata. It would be good to update the bundled python driver and simplify cqlsh code to utilize its capability to parse virtual tables.
