    [API-CHANGE] chart data table implementation
    
    Adds new service DataTable, which is reposible for the properties
    of a data table for a chart. Also removes the existing properties
    related to the data table from Diagram service, which were added
    prematurely in the past, without a data table actually being
    supported by the chart module.
    
    Also adds an implementation of the DataTable service in chart2
    module.
