Add ValkeySession provider for session memory

[daric93]

Description:

Problem

Organizations using Valkey — the Linux Foundation's open-source, Redis-compatible data store — have no first-class session provider in the SDK. While Valkey is wire-compatible with Redis, relying on RedisSession with redis-py means missing out on the dedicated Valkey-GLIDE client, which is optimized for Valkey and will diverge from redis-py as Valkey adds its own features.

Proposed solution

Add a ValkeySession class following the same patterns as RedisSession. It should:

• Implement the Session protocol
• Use valkey-glide (≥2.1) as the client library
• Support from_url factory method (valkey://, valkeys://, redis://, rediss://)
• Support TTL-based session expiration
• Support injecting an existing GlideClient for connection reuse
• Be registered in init.py with lazy import
• Include unit tests, integration tests (testcontainers), and documentation

I'd like to implement this integration if it aligns with the project roadmap and maintainers are interested. Could you please assign it to me?

Thanks for your interest here. We don't have immediate plans to add this one, but if many developers need this, we'll revisit it.
