A cache collector that caches IDs for block_content UUIDs.
As block_content entities are used as block plugin derivatives, it is a fairly safe limitation that there are not hundreds of them, a site will likely run into problems with too many block content entities in other places than a cache that only stores UUID's and IDs. The same assumption is not true for other content entities.
