CockroachDB changefeeds emit resolved timestamps across all the partitions within a topic. We could leverage it, to allow transactional consistency across multiple rows, by staging events and committed them to the target tables once we get the same resolved timestamp on all the partitions.

kafka: adding best effort and transactional consistent modes.
ef6a5cf 
This change adds transactional support to the Kafka connector for CRDB
changefeeds.

The changefeeds broadcast the resolved timestamp to each partition, and we
advance the checkpoint within cdc-sink based on the minimal resolved timestamp
received on all the partitions.

Closes #777.
