Rename log field id to meta_id in case of get_metadata request. This field is string in contrast to message id, which is long.

Rename message_id to time_id. Use _id for sequential message index given by producer and time_id for message based on arrival time.

Fix stream_delete functionality. Now stream metadata, auto_incrementing_id and list of streams are cleaned up.

Add default value for flag detailed of the get_stream_list request value: true. This will restore back-compatibility with old consumer library.

Add boolean parameter `ordered` to request get_next. If True, it returns next by message_id, if not by _id.
