[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.
