Pull Request Overview

This PR implements a new feature to reassign batches to an alternative Kyuubi instance in case the original instance is lost. The changes include the addition of a new DTO class to encapsulate the response of the reassign operation.

• Introduces ReassignBatchResponse DTO with fields for success and message
• Implements standard methods like equals, hashCode, and toString for the new DTO

• [nitpick] Consider renaming 'msg' to 'message' in the DTO for improved clarity and consistency with common naming conventions.

private String msg = null;
