[16.0][ADD] new module pos_check_accounting_settings to avoid launching new PoS session with incorrect configuration.

[legalsylvain]

This module extends the functionnality of Odoo PoS adding extra checks, when opening session, to ensure that accounting configation is correct.

Use case 1

When we create a payment method and if :

• the field 'Outstanding Payment' is not set on payment method
• AND the field 'Outstanding Receipts Account' is not on company

if we use the payment method in the Point of sale, it is not possible to close the session after.

As it not possible to change a payment method when a session is not closed, this bad configuration has to be fixed by SQL.

This module adds a check when opening session, to avoid such situation.
