Changelog Entry

Added Redis Sentinel support for Websockets
Added Redis Sentinel support for AppConfig

Description

The PR adds support for Redis Sentinel failover clusters, allowing for a fully highly available OpenWebUI-Setup. Unfortunately, the implemention needs to work around socketio's lack of support for Redis Sentinel in a somewhat involved way, by creating a class AsyncRedisSentinelManager that inherits from socketio's AsyncRedisManager and bypasses the parent constructor. Otherwise, the Sentinel support from redis-py is used directly.

To avoid adding too many new env variables, WEBSOCKET_REDIS_URL (and REDIS_URL) is maintained as source of Redis configuration, but with the "host" part being used as Sentinel service name.

The code has been tested in a staging environment and is stable.

Added

Redis Sentinel support for Websocket and AppConfig
New envs: WEBSOCKET_SENTINEL_HOSTS, WEBSOCKET_SENTINEL_PORT, SENTINEL_HOSTS, SENTINEL_PORT

Notes

I'm not entirely sure why there are both REDIS_URL and WEBSOCKET_REDIS_URL envs. It seems like the former has only recently been picked up for AppConfig. For the moment, I have correspondingly added two sets of Sentinel environment variables. But because I'm not sure if this is supposed to stay like this, I'm currently holding back on commiting corresponding changes to the documentation.
