[IMP] web: graph: restorable order, stacked & cumulative options

For the Knowledge module, we would like to allow the user to fully
customize a graph view and let the user insert the graph they see in an
article. When loading the graph view from an article, the system can not
currently restore the following settings:

- For the bar chart and the line chart: The system will not able to
  restore the "sorting order" and the "stack option" set by the user.
- For the line chart: The system will not be able to restore the
  "cumulative option" set by the user.

This commit will ensure that these options can be specified from the
context of the view. The context configuration will have a higher
precedence than the configuration stored in the metadata of the model.

When the user will open an article containing a graph view, the graph
view will automatically load the options that have been set by the user
when inserting the view. The user can thus create their own dashboards
by customizing the graphs and inserting them in an article.
