This reverts commit 475c96589ca65282e1a61350271c2f83f0d4044f, reversing
changes made to 705915ab5cf24430892107764b0050c07e1df583.
We decided that this is not worth busting everyone's cache as this
seems like a very unlikely problem. The problem only occurs when the
user is 1) not using a namespace, or 2) using the same namesapce for
different *kinds* of cache items. The recommended "fix" is to put
those cache items into their own namspace:
id = 1
Rails.cache.fetch(id, namespace: "user"){ User.find(id) }
ids = [1]
Rails.cache.fetch(ids, namespace: "users"){ User.find(ids) }
See the discussion on #14269 for details.

* Change the signature of `fetch_multi` to return a hash rather than an
|
|
array. This makes it consistent with the output of `read_multi`.

|
|
* Introduce `Concern#class_methods` as a sleek alternative to clunky
|
|
`module ClassMethods`. Add `Kernel#concern` to define at the toplevel
|
|
without chunky `module Foo; extend ActiveSupport::Concern` boilerplate.
