Unintended HiveConf overriding in Coral leading to query execution auth failures

Problem Description

Coral is experiencing authentication failures when accessing Hive metastore data due to unintended hijacking/overriding of HiveConf objects across different components. Introduced from #503

Current Behavior

HiveToRelConverter uses a properly configured HiveConf from Coral's HiveMetastoreClient wrapper.
CoralParseDriver creates a new, unconfigured HiveConf:
```
HiveConf hiveConf = new HiveConf();
```
This new HiveConf lacks necessary authentication and connection details.
Result: consistent authentication failures with execution-time/run-time errors like "Unable to determine current user".

Expected Behavior

All Coral components should use a consistent, properly configured HiveConf.
Authentication and Hive metastore data access should succeed consistently.

Impact

Query parsing/execution failures

Questions to Consider

Should we expose HiveConf getter/setter methods in Coral's HiveMetastoreClient wrapper (assuming Coral project wrapped around hmsClient to read-only by design)? What are the implications?
Is setting hive.support.sql11.reserved.keywords to false the right approach, or do we need a more flexible solution? Given the significant refactoring required, are there less invasive alternatives that could address this issue? How would these changes impact Coral's modularity, security, and maintainability?
