[13.0]]ADD] Add acconut_invoicing_mode

Add three modules helping on automatically invoicing customers.

The base module `account_invoice_base_invoicing_mode` does not actually
do anything but adds a selection field on partner to allow assigning an
invoicing mode to a customer.

The two other modules add specific invoicing mode.

The module `account_invoice_mode_monthly` creates monthly invoices for
customer on a specific day (configuration is in Accounting Settings)

The module `account_invoice_mode_at_shipping` creates invoices on the
shipping of the goods.

Those modules use queue_job to generate and validate invoices.

+This is a base module for implementing different invoicing mode for customers.
+It adds a selection field `invoicing_mode` in the Accounting tab of the partner
+with a default value (Odoo standard invoicing mode).
+But it serves no purpose installed on its own.
+
+The following modules use it to install specific invoicing mode :

+    * `account_invoice_mode_monthly`
