Support create, update, delete and list Kafka topics via psql client using sql syntax

[jfallows]

Describe the desired outcome from the user's perspective As an appdev, I want to use familiar SQL syntax to manage strongly typed Kafka topics and passthrough to other psql endpoint for other sql statements.

Acceptance criteria

• CREATE TOPIC sql statement to create a Kafka topic with schema (via catalog)
• DROP TOPIC sql statement to delete a Kafka topic with schema
• ALTER TOPIC sql statement to update a Kafka topic schema (via catalog)
• SHOW TOPICS sql state to list Kafka topics with schemas (via catalog)

Note: consider CREATE TABLE style syntax.

Additional context Requires psql binding server and client to proxy to remote psql server, route by command to send CREATE TOPIC etc to specific processing, and psql-kafka binding to map to CreateTopicRequest and DeleteTopicRequest plus catalog support to register new schemas.

See psql protocol specification.
