Greptile Summary

This PR updates the Redis connection setup in the bloom filter example, addressing a deprecated function usage but introducing potential security concerns.

• Replaced deprecated redis.New() with redis.MustNewRedis() in bloom/bloom.go
• Added RedisConf struct with hardcoded Redis host, password, and node type
• Potential security risk: Hardcoded Redis password "redis_6X6RSk" in the code
• Reduced flexibility: Redis configuration now hardcoded instead of being parameterized
• Consider moving Redis configuration to a separate, non-versioned config file for better security and flexibility
