Upstash Redis Python SDK

The `upstash-redis` library is a connectionless, HTTP-based Redis client for Python, specifically designed for serverless and serverful environments where HTTP is preferred over TCP (e.g., AWS Lambda, Vercel, Google Cloud Functions). It provides a simple, Pythonic interface to interact with Upstash Redis databases via their REST API. The SDK is currently in GA stage, receives regular updates and bug fixes, and its latest stable version is 1.7.0.
