refactor/remove-cluster-id: (#220)

### 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.
