bug(cdc-connector): InstanceNotFoundException

[fuyufjh]

Describe the bug

Background: the users stopped the cluster and restarted after a night.

This InstanceNotFoundException shouldn't be occurring, can you help me check it? There are too many of these in the logs, making it hard to find the real errors.

This warn log means the underlying Debezium connector doesn't ready. We are waiting the connector to become ready when we create the shared cdc source job. I'll remove this log in a PR.
