Extended Valkey client introspection functionality about valkey HOT 3 OPEN

Originally reference from redis/redis#12311.

Nit Title: Extended Client Introspection functionality

The default behavior for CLIENT LIST API is all filters, and with that the response payload can be pretty huge. I think valkey-cli kind of gets stuck. With CLIENT DESCRIBE we can look to move away from the text format and have RESP format and get paginated response or adding a default COUNT value to restrict the payload size. I had tried that here redis/redis#11907.

The downside of introducing the new API is maintaining two set of API(s) and no guarantee of administrator(s) of moving to this.

I think you raise a really good point. We could add a pagination functionality by doing client-list based off of ID, and add that to client list. I think we have seen that people generally don't migrate to new commands, so it probably makes more sense to enhanced the ones we have.
