Slow json endpoints without clean integration (they don't use WP_QUERY)

[jeichorn]

At Pagely we have a similar plugin, though maybe less cleanly done. Anyhow we recently ran into slowness on ajax queries to woocommerce_json_search_products_and_variations. This runs queries directly so the only way to override is to replace the json handler.

If you are interested I can put together a pull request, but I don't want to waste anyones time if its considered outside the scope of this plugin.

PR would be great :) Where do those AJAX queries happen?
