Summary
Add type mappings between Avro and Kafka Connect to improve users' visibility into how Avro types eventually resolve to ClickHouse data types. Also, add the current (evolving) list of unsupported Avro data types based on the findings in ClickHouse/clickhouse-kafka-connect#697 (issue: ClickHouse/clickhouse-kafka-connect#635).
