This commit changes the computation of product having a negative forecasted
quantity to create manual orderpoints. The issue was that each replenish
location needed multiple `_read_group` on `stock.quant` and `stock.move`
on all storable product.
This commit makes only 3 `_read_group`s for all products x locations and
post process the group and quantity sum by location in Python.
This method gives some performance gain in time as well as in memory
consumption
