Refactor config for Unity Catalog connector

[mars-lan]

🤔 Why?

Refactor the config to support both Databricks cluster & SQL warehouse and to better match Unity Catalog's terminology: https://docs.databricks.com/en/integrations/compute-details.html

🤓 What?

• Replace host, cluster_path, and warehouse_id with hostname & http_path.
• Update README files

🧪 Tested?

Verified against a production instance using the new config fields.

☑️ Checks

• Not bumping up to 0.14 until all breaking changes are merged.
