docs: Connect to an AWS API via boto3 low-level client and set ``self.conn``
          to the `boto3.client <https://boto3.readthed
          ocs.org/en/latest/reference/core/boto3.html#boto3.client>`_ object
          (a ``botocore.client.*`` instance). If ``self.conn`` is not None,
          do nothing. This connects to the API name given by ``self.api_name``.
