tools (common/data_objects): metadata parsing in BlogItems:
metadata are parsed to deserialise some well known values like rsm index and count, and some properties have been added to have easier access.
A "complete" property (or item in metadata) is set to True if we are on the last page, False if we are not, or None if we don't have enough data to know if we are on the last page or not.
