Which use case/requirement will be addressed by the proposed feature?

Allow configuring connector to send incremental snapshot completion notifications into a Kafka topic.

Implementation ideas (optional)

Add an optional configuration property to switch between logging snapshot completion status (LogSnapshotStatusNotifications - default) and sending the notification into a Kafka topic (KafkaSnapshotStatusNotifications).

A Kafka notification format:

{{Key = `test_connector` }}
Value = `{"id" : "1b8d98f4-53ec-4beb-aa14-73ea35f185e7", "type":"incremental-snapshot", "data-collections": "schema1.table1", "additional-condition" : "updated_at>='2022-09-20'", "status" : "SUCCEEDED"}`

Snapshot completion statuses:
{{}}

EMPTY,
NO_PRIMARY_KEY,
SQL_EXCEPTION,
