    Making main async

    The initializers for Helm attempt to schedule tasks in the event loop,
    but now that we are not starting one explicitly and passing it around,
    we need to have a loop already started at the time of constructor.

    By making start() async, there is a running loop, and functions like
    k8s_helm_conn.py (~ #81) can call asyncio.create_task
