Refactor: reenable root_path as config parameter

[99Lys]

Summary

Reenable root_path and respective aliases as config parameters.

Description

Currently, in order to set custom schemas for specific models, we use the config parameter schema (and respective aliases).

However, in the current implementation, dremio_space_folder / schema are both effective regardless of the materialization type (and object_storage_path / root_path were disabled). Since, in our adapter's context, schema typically belongs to views, it can be confusing to use only one term for all materialization types.

Therefore, in order to maintain consistency and be compliant with dbt standards, we will refactor how custom schemas can be set by following our internally defined aliases, i.e.:

• schema and respective aliases - if used in config, will only be effective if the model is a view

• root_path and respective aliases - if used in config, will only be effective if the model is a table

Both will behave the same way: append the value provided in config to the respective original one in profiles.yml.

Test Results

• Refactored test test_nested_schema.py
• Updated test_exact_search.py to use the correct config (replaced schema to root_path)

Changelog

• Added a summary of what this PR accomplishes to CHANGELOG.md

Pull request overview

This PR refactors the configuration parameter handling to differentiate between schema (for views) and root_path (for tables), making the adapter more consistent with dbt standards and less confusing for users.

Key changes:

• root_path config now only applies to table materializations and is appended to the default root_path from profiles.yml
• schema config now only applies to view materializations and is appended to the default schema from profiles.yml
• Profile template hints updated to reflect the correct alias mappings
