💥 Breaking changes
* By default `AMQPClient.send_command()` will await the command itself when the method is awaited. This means that `cmd = await client.send_command('my_actor', 'ping')` will await until the `ping` finishes and the replies are received. The previous behaviour can be forced with `await_command=False`, e.g., `cmd = await (await client.send_command('my_actor', 'ping', await_command=False))`. In general this should not be a breaking change since awaiting a done command will return immediately, but it's marked as breaking since in some corner cases there could be some unexpected behaviour.
✨ Improved
* Added an `internal` argument in `CluCommand` that marks the received command as internal.
* Bump `unclick` to `0.1.0b4`.
🏷️ Changed
* When a command status changes to running, the status is emitted as internal.
