Add a new sibro_feature Discount. OFF by default. If ON, then during Add/Edit Policy, we should be able to give a discount to customers.
If discount provided, show that along with Policy Premium in Bracket & in small tag at Client Accounts & Balance Due Report. Adjust Balance Amount accordingly.
If discount provided, then, when we do [Add Premium] from converted, the amount suggested should subtract for the discount amount.
Discount should show up as a new column in Business Statement Download. (Note that Discount is Illegal in some countries; so the column should not show up in Business Statement, if the sibro_feature is OFF)
