* Add article's record key to Fastly Surrogate-Key to separate caches
After #4744 we successfully setup an auto purging system based on Fastly's surrogate key based cache and purging API.
Unfortunately this worked only in the `:show` action as comments are their own tree-based resource.
The `:index` though, is related to a single article, so without the article's record key in the `Surrogate-Key` header the first time we hit the API the result would become the value stored in Fastly's API, for all articles.
* Fix commentable mock for job spec
* Add comment.commentable.purge to the worker as well
* Add more thorough tests for commentable
This job was replaced by the worker with the same name as the suffix
Worker instead of Job, it was kept to run the existing jobs before it
can be fully removed
* Refactored Pages::BustCacheJob to Pages::BustCacheWorker
* Removed Pages::BustCacheJob and specs

* Turn CacheBuster into a module
This class used no internal state, so repeatedly creating short-lived objects seems wasteful.
* Consistently use string interpolation and parenthesis
* Destructure arrays into meaningful names, formatting
* Fix request spec for internal classified listings controller
Interestingly this works when asserting directly on the module, but not on a double.
Asserting directly in the module seems sufficient for this test so the indirection
was removed.
