chore: add option for arrow flight compression mode (#6283)

Browse Source 
* chore/enable-flight-encoder:
 ### Add Flight Compression Support

 - **Configuration Updates**:
   - Added `grpc.flight_compression` option to `config/config.md`, `config/datanode.example.toml`, and `config/frontend.example.toml` to specify compression modes for Arrow IPC service.

 - **Code Enhancements**:
   - Updated `FlightEncoder` in `src/common/grpc/src/flight.rs` to support compression modes.
   - Modified `RegionServer` and `DatanodeBuilder` in `src/datanode/src/datanode.rs` and `src/datanode/src/region_server.rs` to handle `FlightCompression`.
   - Integrated `FlightCompression` in `src/servers/src/grpc.rs` and `src/servers/src/grpc/flight.rs` to manage compression settings.

 - **Testing and Integration**:
   - Updated test utilities and integration tests in `tests-integration/src/grpc/flight.rs` and `tests-integration/src/test_util.rs` to include `FlightCompression`.

* chore/enable-flight-encoder:
 ### Enable Compression in FlightClient

 - **`client.rs`**: Updated `make_flight_client` to accept `send_compression` and `accept_compression` parameters, enabling Zstd compression for sending and receiving messages.
 - **`client_manager.rs`**: Modified `datanode` method to pass compression settings from `ChannelConfig` to `RegionRequester`.
 - **`database.rs`**: Adjusted calls to `make_flight_client` to include compression parameters.
 - **`region.rs`**: Updated `RegionRequester` to store and utilize compression settings.
 - **`frontend.rs`**: Configured `ChannelConfig` to enable compression based on options.
 - **`channel_manager.rs`**: Added `send_compression` and `accept_compression` fields to `ChannelConfig` with default values and updated tests accordingly.

 ### Update Compression Defaults and Documentation

 - **Configuration Files**: Updated `datanode.example.toml` and `frontend.example.toml` to include a default setting comment for `flight_compression`, specifying it defaults to `none`.
 - **gRPC Server Code**: Modified `grpc.rs` to set `None` as the default for `FlightCompression` instead of `ArrowIpc`.
