Description

Migrated from DBZ-3633

Db2ConnectorTest.java checks only for correct values in connector config. However, these values often have prefixes that need to be stripped (e..g. Db2Connection expects a subset prefixed "database."). Maybe we should have a test which will actually try to validate the connection.

Contributor guide

Research direction
Inspect the existing Db2ConnectorTest and Db2Connection classes to understand how config values are prefixed. Then write a test that actually attempts to validate a Db2 connection, ensuring prefix stripping works correctly.
