test: add Redis Sentinel container setup for testing

- Add `setupRedisSentinelContainer` function to set up a Redis Sentinel container for testing
- Add Redis Sentinel setup steps in `TestRedisSentinel` test function
- Remove hardcoded Redis Sentinel hosts in `TestRedisSentinel` and dynamically generate them based on container setup
