* feat/otel-arrow:
### Add OpenTelemetry Arrow Support
- **`Cargo.toml`, `Cargo.lock`**: Updated `otel-arrow-rust` dependency to use a local path and added `arrow-ipc` as a dependency.
- **`src/servers/src/grpc.rs`, `src/servers/src/grpc/builder.rs`**: Integrated `ArrowMetricsServiceServer` with gRPC server, including support for custom header interception and message compression.
- **`src/servers/src/otel_arrow.rs`**: Implemented `OtelArrowServiceHandler` for handling OpenTelemetry Arrow metrics and added `HeaderInterceptor` for custom header handling.
* feat/otel-arrow:
Add error handling for OpenTelemetry Arrow requests
- **`src/error.rs`**: Introduced a new error variant `HandleOtelArrowRequest` to handle failures in processing OpenTelemetry Arrow requests.
- **`src/otel_arrow.rs`**: Implemented error handling for receiving and consuming batches from the OpenTelemetry Arrow client. Added logging for errors and updated the response status accordingly.
* feat/otel-arrow:
Remove `otel_arrow` Module from gRPC Server
- Deleted the `otel_arrow` module from the gRPC server implementation.
- Removed the `otel_arrow` module import from `grpc.rs`.
- Deleted the `otel_arrow.rs` file, which contained the `OtelArrowServer` struct and its implementation.
* feat/otel-arrow:
## Remove `Arc` Implementations for Protocol and Pipeline Handlers
- **Removed `Arc` Implementations**: Deleted `Arc` implementations for `OpenTelemetryProtocolHandler` and `PipelineHandler` traits in `query_handler.rs`. This change simplifies the code by removing redundant async trait implementations for `Arc<T>`.
- **File Affected**: `src/servers/src/query_handler.rs`
* feat/otel-arrow:
Improve error handling and metadata processing in `otel_arrow.rs`
- Updated error handling by ignoring the result of `sender.send` to prevent panic on failure.
- Enhanced metadata processing in `HeaderInterceptor` by using `Ok` to safely handle `grpc-encoding` entry retrieval.
* fix dependency
* feat/otel-arrow:
- **Update Dependencies**:
- Moved `otel-arrow-rust` dependency in `Cargo.toml`.
- Adjusted workspace dependencies in `src/frontend/Cargo.toml`.
- **Error Handling**:
- Removed `MissingQueryContext` error variant from `src/servers/src/error.rs`.
