How to setup a multi-node pingora cluster ?

[pulkitsharma07]

Hi, I am trying to understand if pingora can be used in distributed environments, i.e. multiple pingora instances spread across different servers. Specifically I wanted to know about the rate-limiting capabilities provided by : https://github.com/cloudflare/pingora/tree/main/pingora-limits, does it support a "backend" for storing rate limits ?

Usually this is achieved using some common storage backend (like redis, or memcached), so that the rate limiting counters can be shared by different instances of a server.
