This is another implementation of !789
Instead of copying the Open Sale Order logic, this MR directly uses Open Internal Order to generate monthly movements for Instances and Nodes. Those Internal movements will NOT be linked to the customer.
Then, there will be 1 alarm gathering the Internal Packing List movements into a single monthly Sale Packing List per customer (using an Order Builder).
This is still work in progress, as !750 will also be integrated to use this design
