Feature Request: Redis sentinel password support

[xinxinran0221010]

I am encountering an issue when I am trying to use split-synchronizer, which uses go-split-common library.

In my environment, Redis is deployed as cluster mode and sentinel mode is enabled with sentinel password.

When I passed the Redis settings to split-synchronizer, I got "Unauthenticated" error from Redis. After troubleshooting, I found it caused by incorrect sentinel password.

Currently go-split-common doesn't support sentinel password, while the dependency package splitio/go-toolkit supports this setting (https://github.com/splitio/go-toolkit/blob/main/redis/types.go#L25).

So could you please try to add this SentinelPassword parameter support?

As my investigation, just adding two lines in 2 files respectively is enough:

• Add new code SentinelPassword string after:
  

  go-split-commons/conf/conf.go

  Line 46 in 82c4b0f

  SentinelMaster string

• Add new code universalOptions.SentinelPassword = config.SentinelPassword after:
  

  go-split-commons/storage/redis/redis.go

  Line 48 in 82c4b0f

  universalOptions.Addrs = config.SentinelAddresses
