What Debezium connector do you use and what version?

MongoDB Connector

Description

Debezium Connector doesn't use readConcern parameter currently. In case of sharded cluster, snapshot data will be inconsistent as it will be determined by readConcern set by database/collection. Connector should use "snapshot" read concern as stated in mongodb docs - https://www.mongodb.com/docs/manual/reference/read-concern-snapshot/, so that consistent snapshot data is read.
