Create eCommerce Provider for Faker library

[kloon]

Currently, we make use of the standard Faker providers when generating data, this data is not really suited for things like product names, categories, tags and attributes.

Implement something along the lines of https://github.com/mbezhanov/faker-provider-collection/blob/master/src/Faker/Provider/Commerce.php which creates a new provider for eCommerce specific functionality to generate more meaningful product data.
