Added configuration to not make a request related to sales for each variant in the detail of a product

[jlachancekffein]

What are you trying to do?

In the administration panel, when viewing the detail of a product, a request is made for each variant in order to return the related sales.

This causes a problem when there are several variants for a single product.

What's your proposed solution?
It would be interesting to have a configuration option to display or not this functionality.

For now, in order to work around the problem, I am getting each request to determine if it is a request with request queryParam ('p') === 'admin/actions/commerce/sales/get-sales-by-purchasable-id '.

If so, I directly return a void-type response to prevent sql query.

This is now fixed in the latest release: 3.2.13
