Feature: Clerk.io

[bjarnef]

I don't have the discussions tab for this repository, so I submitted this feature request as an issue.

I noticed integration with Algolia here:
https://marketplace.umbraco.com/package/umbraco.cms.integrations.search.algolia

From time to time I have come across Clerk.io and used it in some Umbraco projects.
I wonder if it makes sense to add integration for this and would be useful if it integrated well with Umbraco Commerce, e.g. to show trending products in a category, related products on product page and popular products on home page.
