### Remove `cluster_id` Field from Protocol Buffers
- **Removed `cluster_id` Field**: The `cluster_id` field has been removed from the `RequestHeader` and `ResponseHeader` messages across multiple langua
bindings and source files. This includes updates to:
- C++: `common.pb.cc`, `common.pb.h`
- Go: `common.pb.go`
- Java: `Common.java`
- Proto: `common.proto`
- Rust: `meta.rs`
These changes streamline the protocol by eliminating the `cluster_id` field, simplifying the message structures and related logic.
