[16.0][ADD] account cutoff accrual on order

[jbaudoux]

Port and refactor #73

Generate cutoff accruals by analyzing order lines invoiced & delivered quantity (or ordered quantity for sales with invoice policy on order).

Several modules are provided:

• account_cutoff_accrual_order_base: Base module to analyze any type of order lines
• account_cutoff_accrual_order_stock_base: Base module to analyze order lines delivered by stock moves
• account_cutoff_accrual_sale: analyze sales order lines to accrue what must be invoiced. Generates accrued revenue, i.e. invoice to establish
• account_cutoff_accrual_purchase: analyze purchase order lines to accrue what must be invoiced. Generates accrued expense, i.e. invoice to receive
• account_cutoff_accrual_sale_stock: analyze sales order lines to accrue what must be delivered. Generates accrued prepaid revenue, i.e. goods to deliver
• account_cutoff_accrual_purchase_stock: analyze purchase order lines to accrue what must be received. Generates accrued prepaid expense, i.e. goods to receive

The modules allow to process a large amount of data in a reasonable amount of time. To decrease the amount of stock moves & invoices to analyze a cron pre-generates the cutoff entries at the end of the period. Nevertheless, it is always possible to regenerate entries at any time (but the more stock moves & invoices to analyze are, the more time it will take). Any invoice posted after the cutoff is generated will alter the corresponding cut-off entries. Once the cut-off is posted is accounting, you cannot anymore alter the entries.

Note: Those modules covers the feature provided by stock_cutoff_picking but in a more generic and efficient way. Instead of analyzing all pickings & invoices inside a given interval, only pickings and invoices generated after the cutoff date are analyzed,
The limit in time in the past is then now disabled.

Accrual on order flagged as force_invoiced is disabled.

Road-map: The generic approach of the modules allows to extend the features to generate accrual on service SO / PO with project tasks

Hi @alexis-via,
some modules you are maintaining are being modified, check this out!

[jbaudoux]

@alexis-via Added dependencies on sale/purchase_force_invoiced to handle exclusion. I dropped my boolean in favor of that force_invoiced

[jbaudoux]

I added the use case where a SO having only the delivery line (shipping cost) to invoice among the SO lines is not considered as invoiceable.

@alexis-via Have you had the chance to test this PR in comparison to your previous implementation ? Can it get merged ?
