Merge run_task handling

[tpoliaw]

Update the client's run_task method to use stomp if the configuration is present
and fall back to the new websocket connection if not.

Allows the scripting interface (bc.plans.count(...)) to run without
configuration using websockets.

The CLI also defaults to websockets if no configuration is present. To force
stomp monitoring, a new --stomp flag is added to be paired with the --ws flag.

The previous run_task method on BlueapiClient has been renamed to run_stomp and
run_task will delegate to the correct method depending on the configuration
available. This should not be a breaking change as there is no change in
behaviour if configuration is present.
