Show quantity size for Commodities

@siva
Kindly show Unit size (not lot size) for commodity futures when placing the order.

Example - CrudeoilM, 1 Lot is “10 Units”, whereas for Crudeoil 1 lot is “100 Units”

Below is a screenshot from Dhan that has a similar feature.
Very convenient, and helps understand what position size one will have.

But if one see in market depth it still shows in lots only, showing different units can confuse users, also people who trade these are aware how much one unit move will be in pnl, even we show that in info widget on context menu.
