Implement the hydra_provider GRPC server

[seofernando25]

hydra_provider is currently using a stub implementation for the GRPC server.

We would like to have an exposing API that allow us to:

• Check the current running configuration of hydra_provider (health and status)
• Change configurations (set data mode: random, serial port, idle; select a desired serial port, set baud rate, etc)

And optionally a simple UI front-end for it.

It seems that a quite big refactor would have to be made for it to work as the currently hydra_provider architecture doesn't allow it.

Thinking about it, it would be interesting if

• hydra_provider without any arguments starts in an IDLE / DISCONNECTED mode
• And we could either:
  • Use the Web UI to manually change it to random/serial/idle modes and passing their proper config
  • Use the CLI args to override the default idle mode on start-up

Thoughts?

Yeah I'm adding that. So basically the cli only takes a port for serving. Everything else is configured through the api endpoints.
