Pull Request Overview
This PR refactors the codebase to use a unified HTTP client across all HTTP operations in the Databricks SQL connector. The primary purpose is to consolidate HTTP client usage, eliminating various singleton HTTP clients and direct requests library usage in favor of a single UnifiedHttpClient based on urllib3.
Key changes:
- Introduced
UnifiedHttpClientclass that provides a centralized HTTP client with retry policies, connection pooling, SSL support, and proxy support - Removed singleton HTTP clients (
DatabricksHttpClient,TelemetryHttpClient) and replaced directrequestsusage - Updated all components (auth, telemetry, staging operations, cloud fetch, feature flags) to use the unified client
