Bump redis-rs + Route Function Stats to all nodes #2117

First of all - why should we have different response policy between standalone and cluster mode?
Second - this whole change shouldn't be under value conversion, but under standalone_client.rs::send_request_to_all_nodes. We already have response policy that matches this case if we decide to aggregate the responses: FirstSucceededNonEmptyOrAllEmpty.
But we should decide whats our approach here and we probably would like to keep unified experience over standalone and cluster mode. Is it possible in standalone that a script will run both on the primary and on a replica? or on multiple replicas? seems to me like we're going to loose information if we'll do this aggregation

Is it possible to do the same test in node and java?
I can help you with java part if needed.

Since we've modified the FUNCTION STATS command to return responses from all nodes (instead of only from primaries), the response structure for standalone setups will change. Instead of returning a single response from a random node, it will now return a map of responses, where each key is the node's address and the value is the same node's response. Even in standalone mode.
Reason for the Change:
The main reason for this change is that a function or script could be running on a replica, and the previous FUNCTION STATS command wouldn't detect it, resulting in an incomplete response.
