[IMP] mrp: operations listview

On the MRP operation model (`mrp.routing.workcenter`):

  - Changes the order (ordered by workcenter and BOM in priority);

  - Adds computed field, `time_computed_on`, which is only used in list
    view (display on how many numbers of work orders the duration is
    computed);

  - Adds multiple fields in list view (often optional display);

  - Adds two groupby (by BOM and by workcenter).
