class OrderNumberSubscriber in Commerce Core 8.2

Generates the order number for placed orders.

Modules wishing to provide their own order number logic should register an event subscriber with a higher priority (for example, 0).

Modules that need access to the generated order number should register an event subscriber with a lower priority (for example, -50).
