Stock Warehouse Security

With this module you are able to set a restricted list of allowed
warehouses that user can see and operate with.

This module is inspired from the experiences of
[stock_warehouse_security](https://github.com/akretion/stock-logistics-warehouse/tree/12-muli-wh-security/stock_warehouse_security/)
on version 12.0 but has some key differences on user experience:

- In this module there is no new groups, user is able to see allowed
  warehouses only or all if not set.
- So in this module there is no "current warehouse" concept on user ( in
  v12.0 that module was based on
  [base_multi_warehouse](https://github.com/akretion/stock-logistics-warehouse/tree/12-base-multi_warehouse/base_multi_warehouse)
  which allowed users to switch between warehouses).
