Add a Swatches cache

[gsa83]

Description (*)

In order to improve Magento 2 capacity to absorb a big amount of charge, I think one of the most important improvement to do is to add a new dedicated cache for the Swatches. Whatever the website that uses M2 swatches, PLP, and PDP displays is dependant on the async load of the JSON of the swatches. The calculation of the JSON is causing a big part of the server charge and limit the capacity of M2 to scale up.

Expected behavior (*)

Add a new cache call "swatches caches", with by default a 1h lifetime to load PDP ad PLP really faster. This cache may be ideally served by Redis.

Benefits

Improve Magento 2 PLP, and PDP load time, and improve Magento 2 capacity to support a bigger charge.
