Description of the issue/feature this PR addresses:
Currently, we cannot display prices per unit (for example $/kg, etc.)
on products shown in the shop. This is important for any eCommerce
business that sells something other than units, or just for informational
purposes.
Desired behavior after PR is merged:
Allows the user to add unit measurements for products. This behaviour is
disabled by default, and can be enabled through the settings page by
activating "eCommerce Base Unit Price" option.
Enabling it displays a price per unit field in /shop's product page,
comparison tool and cart. The price per unit of measurement is
automatically computed and can be displayed both on the product,
the cart and the comparison pages.
Enabling it also modifies the product's configuration page to include
what unit of measure to display in the price per unit field, as well
as the number of units used to calculate the price per unit.
