[skip ci] Inventory api: interpolation + group by time sequence

TODO:

• proper name one_for_all / all_or_nothing interpolations
• add interpolation support to getMovementHistoryList
• cleanup the changes in SimulationTool
• demonstrate a use in erp5_project or erp5_calendar
• SimulationTool_zGetInterpolationMethod should be usable by anonymous. Check missing tests for anonymous use of inventory API. ( changed SimulationTool_zGetInterpolationMethod use database method to Anonymous )

Discussion vincent:

• names interpolation: floor, ceil, greedy
• group_by_sequence_dict = {'key1': {'from_date': ...}, 'key2':}
