[OBJECT] Support OBJECT type in iotdb

[JackieTien97]

This pull request introduces support for object data types and improves BLOB/object handling in the integration test framework, along with some minor configuration and utility enhancements. The most significant changes are the addition of a comprehensive integration test for object queries, the implementation of object limit configuration, and the enhancement of BLOB retrieval in clustered result sets.

Object Data Type Support and Testing:

• Added a new integration test class IoTDBObjectQueryIT.java to verify object and BLOB column handling, including JDBC and session API behaviors, error cases, and correct value retrieval.

Configuration Enhancements:

• Added a setRestrictObjectLimit(boolean) method to the CommonConfig interface and its implementations (MppCommonConfig, MppSharedCommonConfig, RemoteCommonConfig), allowing tests to configure object limits in cluster environments. [1] [2] [3] [4]

Test Framework Improvements:

• Implemented the getBlob(int) and getBlob(String) methods in ClusterTestResultSet to aggregate and compare BLOB results across multiple result sets, replacing the previous unsupported operation. [1] [2]

Utility and Minor Fixes:

• Added a utility method getDataNodeObjectDir() in DataNodeWrapper to retrieve the object directory path for a data node.
• Updated example usage in TableModelSessionPoolExample.java to insert a null value for the plant_id column.
