Module polkadot_runtime_parachains::assigner_on_demand

The parachain on demand assignment module.

Implements a mechanism for taking in orders for pay as you go (PAYG) or on demand parachain (previously parathreads) assignments. This module is not handled by the initializer but is instead instantiated in the construct_runtime macro.

The module currently limits parallel execution of blocks from the same ParaId via a core affinity mechanism. As long as there exists an affinity for a CoreIndex for a specific ParaId, orders for blockspace for that ParaId will only be assigned to that CoreIndex. This affinity mechanism can be removed if it can be shown that parallel execution is valid.
