Deletes all relations that link the product id to other products under the relation definition relationId,
in a single call. Use this to clear a whole relation type at once. To remove only specific related products,
delete a single pair with DELETE /products/{id}/connections/products/{relationId}/{connectedProductId}, or a
selected subset with DELETE /products/{id}/connections/products/{relationId}/bulk.

For more details on working with products and
relations, refer to the Add product relations.
