        # List information about objects in an S3 bucket
        #
        # ==== Parameters
        # * bucket_name<~String> - name of bucket to list object keys from
        # * options<~Hash> - config arguments for list.  Defaults to {}.
        #   * 'prefix'<~String> - limits object keys to those beginning with its value.
        #   * 'marker'<~String> - limits object keys to only those that appear
        #     lexicographically after its value.
        #   * 'max-keys'<~Integer> - limits number of object keys returned
        #   * 'delimiter'<~String> - causes keys with the same string between the prefix
        #     value and the first occurence of delimiter to be rolled up
        #
        # ==== Returns
        # * response<~Excon::Response>:
        #   * body<~Hash>:
        #     * 'Delimeter'<~String> - Delimiter specified for query
        #     * 'Marker'<~String> - Marker specified for query
        #     * 'MaxKeys'<~Integer> - Maximum number of keys specified for query
        #     * 'Name'<~String> - Name of the bucket
        #     * 'Prefix'<~String> - Prefix specified for query
        #     * 'Contents'<~Array>:
        #       * 'ETag'<~String>: Etag of object
        #       * 'Key'<~String>: Name of object
        #       * 'LastModified'<~String>: Timestamp of last modification of object
        #       * 'Owner'<~Hash>:
        #         * 'DisplayName'<~String> - Display name of object owner
        #         * 'ID'<~String> - Id of object owner
        #       * 'Size'<~Integer> - Size of object
        #       * 'StorageClass'<~String> - Storage class of object
