    Cancelling the returned future.Future does not tell the given
    implementations.Channel to abandon attempts it may have been making to
    connect; cancelling merely deactivates the return future.Future's
    subscription to the given implementations.Channel's connectivity.

    Args:
      channel: An implementations.Channel.

    Returns:
      A future.Future that matures when the given Channel has connectivity
        interfaces.ChannelConnectivity.READY.
