ComponentInformation plugin "UNIMPLEMENTED"

When running the attached code, and connecting to the headless px4 docker container (jonasvautherin/px4-gazebo-headless) I receive this error.

Traceback (most recent call last):

Based on a prior reported issue (#394), I think this might be some simple issue with the library.

Code

import asyncio
from mavsdk import System
from typing import List
from mavsdk.component_information import FloatParam


async def run():

    drone = System()
    await drone.connect(system_address="udp://:14540")

    float_params : List[FloatParam] = await drone.component_information.access_float_params()

    for param in float_params:
        print(param)


if __name__ == "__main__":
    # Start the main function
    loop = asyncio.new_event_loop()
    asyncio.set_event_loop(loop)
    loop.run_until_complete(run())

I think I didn't want to expose the component information plugins in Python yet because it was still work in progress. I had done an initial implementation in C++ but the protocol had slightly changed after that, and I haven't had time to work through that yet.

Plus, the language wrappers might not yet properly work with server plugins. I need to verify that too.
