### Search before asking

- [X] I had searched in the [issues](https://github.com/apache/kvrocks/issues) and found no similar issues.

### Motivation

https://redis.io/docs/latest/commands/?group=connection

There's many `CLIENT` subcommands that we can evaluate and see if we can support in Kvrocks, like `CLIENT ID/KILL/INFO/LIST/CACHING...`.
