[MatteoPologruto]

Motivation

Add gRPC daemon support for the list function.

Change description

Add gRPC daemon support for the list function.

Additional Notes

It can be tested following these steps:

1. Open a terminal.
2. Start the Arduino Flasher CLI gRPC daemon:

$ arduino-flasher-cli daemon

Daemon is now listening on 127.0.0.1:50052
{"IP":"127.0.0.1","Port":"50052"}

3. Open another terminal.
4. Run the following grpcurl command in the new terminal to create a gRPC client instance:

$ grpcurl \
  -plaintext \
  -import-path ./rpc \
  -proto cc/arduino/flasher/v1/commands.proto \
  127.0.0.1:50052 \
  cc.arduino.flasher.v1.Flasher.List
