This diff removes the old legacy API methods from the Tunnelbroker API including the proto file and calls from the native codebase.
Old legacy API methods that should be removed:
- CheckIfPrimaryDeviceOnline
- BecomeNewPrimaryDevice
- SendPong
These methods were added prior 0.1 and are not used anymore.
These diff changes take place in:
- The protobuff file and its generated ones - by removing the API calls;
- Native C++ network client-related codebase - by removing the API-related methods;
- Tunnelbroker Rust gRPC server - by removing the empty handlers for the old API.
