This commit introduces `bindgen-cli` installation and sets up `BINDGEN_EXTRA_CLANG_ARGS` passthrough in `Cross.toml`. It also updates the pre-build process with necessary packages (`clang`, `libclang-dev`), alternative compilers, and adds `aws-lc-rs` with `bindgen` support to `workflow-runner` dependencies.
This commit updates multiple dependencies, including:
- `axum` upgraded to 0.8 for HTTP and webhook functionality.
- `tonic` upgraded to 0.14 for gRPC support.
- `prost` upgraded to 0.14 for protobuf processing.
- Addition of `tonic-prost` and `tonic-prost-build` for updated gRPC build configurations.
Relevant Cargo.toml entries and `build.rs` are adjusted to reflect these updates.
This commit introduces gRPC-based log streaming between the VM runner (`solstice-runner`) and orchestrator. Key updates include:
- Implemented gRPC server in the orchestrator for receiving and processing runner logs.
- Added log streaming and job result reporting in the `solstice-runner` client.
- Defined `runner.proto` with messages (`LogItem`, `JobEnd`) and the `Runner` service.
- Updated orchestrator to accept gRPC settings and start the server.
- Modified cloud-init user data to include gRPC endpoint and request ID for runners.
- Enhanced message queue logic to handle job results via `publish_job_result`.
- Configured `Cross.toml` for cross-compilation of the runner.
