[FIX] sale_coupon: Don't update automatic rewards on the fly

Purpose
=======

Currently we are updating the coupon rewards on the fly when creating/modifying/deleting a sales order line.

To avoid multiple searches on res_partners and product to know whether the customer/product is valid on the sale coupon program, we store the applicable customers and products on the program according to the domain defined on it.

This brings 2 issues:
- The customers/products stored on the program are not updated (Was the original spec)
- The checks are numerous and maybe overkill for the given results

Specification
=============

- Don't recompute the reward lines on SO modifications. Add a button to compute the line by hand and make an automatic compute on the SO validation or on the page shop/payment.

- When recomputing the reward lines, make a search on the res_partners and products instead. Now that the action is not triggered so often we can afford to make a search.

- Don't use the fields rule_partners_domain and rule_products_domain. This should be removed in master.

- The field is_public_included is useless now. And we decided to make the coupon available for all the partners if they fit the domain on the program.
