In order to add your own external provider, follow these steps:
1. Create your model MyProvider that _inherit 'delivery.carrier'
2. Extend the selection of the field "delivery_type" with a pair
('<my_provider>', 'My Provider')
3. Add your methods:
<my_provider>_rate_shipment
<my_provider>_send_shipping
<my_provider>_get_tracking_link
<my_provider>_cancel_shipment
(they are documented hereunder)
