class PriceListItemAccessControlHandler in Commerce Pricelist 8

Provides an access control handler for price list items.

Price list items are always managed in the scope of their parent (the price list), so they have a simplified permission set, and rely on parent access when possible:

• A price list item can be viewed if the parent price list can be viewed.
• A price list item can be created, updated or deleted if the user has the "manage $bundle price_list" permission.

The "administer commerce_pricelist" permission is also respected.
