Redis sentinel support

[doc-sheet]

Hello.

Since 0.23.1 redis-rs supports sentinel.
Could you add it to relay please?

Hey,

thanks for opening the issue!

Could you, please, provide more context for this feature request?
Why do you need it? How that will help you with using the Relay? Any specific issue it will solve for you?

It will give us more information to consider before plan it out and putting the work on our roadmap.

Sure.
I want to setup failover for redis connection. Sentinel is way simpler than redis cluster and supports select db statement so i can point whole sentry stack to the same redis machines.

Other (python) services can be configured to use sentinel with a bit of code in config but relay is the one where i need to manually update redis server address when db instance crashes.

On the other hand redis-rs now have native support for sentinel so relay could be much more stable in that scenario.

Thanks for the additional context!
I will bring this up to the team for discussion and followup actions.
