When an attribute is missing the current message is unclear about which
class is missing the attribute, especially when there are multiple
classes that could miss the attribute.
By adding the classs name to the error message it is easier to debug:
```ruby
user = User.first
user.pets.select(:id).first.user_id
=> ActiveModel::MissingAttributeError: missing attribute 'user_id' for Pet
```
This also makes the error message more inline with the
UnknownAttributeError message:
```ruby
=> ActiveModel::UnknownAttributeError: unknown attribute 'name' for Person
```

Now that we support a way to register custom configurations we need to
allow applications to find those configurations. This change adds a
`config_key` option to `configs_for` to find db configs where the
configuration_hash contains a particular key.
I have also removed the deprecation for `include_replicas` while I was
in here to make the method signature cleaner. I've updated the upgrade
guide with the removal.
All Rails frameworks deprecators have "Rails" as their `gem_name`, and
the `:notify` behavior emits events based on that, so all frameworks
emit their deprecations under the `rails` namespace.
For example: activesupport/lib/active_support/deprecator.rb:5
activesupport/lib/active_support/deprecation.rb:42
activesupport/lib/active_support/deprecation/behaviors.rb:39
Before, it was using the configured by Rails. Having a mechanism to configure it
for Active Record encryption makes sense to prevent problems with encrypted content
when the default in Rails changes.
Additionally, there was a bug making AR encryption use the older SHA1 before
`ActiveSupport.hash_digest_class` got initialized to SHA256. This bug was exposed
by https://github.com/rails/rails/pull/44540. We will now set SHA256 as the standard
for 7.1+, and SHA1 for previous versions.
With the universal adoption of UTF-8 in browsers, user facing text can
use more optimal Unicode typography. In digital and print design, using
RIGHT SINGLE QUOTATION MARK (U+2019) is normally preferred over
APOSTROPHE (U+0027) in contractions.
For details, see the Unicode Standard Section 6.2:
https://www.unicode.org/versions/Unicode13.0.0/ch06.pdf
> Punctuation Apostrophe. U+2019 right single quotation mark is
> preferred where the character is to represent a punctuation mark, as
> for contractions: “We’ve been here before.” In this latter case,
> U+2019 is also referred to as a punctuation apostrophe.
YAML is great for configuration and such, but for serializing arbitrary
data it has many problem, both in term of performance and efficiency
but also in term of security.
As such, we shouldn't let it be the default.
The open question is wether we should provide another default, or
just let users chose what they want based on their own tradeoffs.
Many people would probably suggest JSON as the new default, unfortunately
I don't think it's a good fit either because the parsers available in
Ruby have some wonky behaviors:
```ruby
>> ActiveSupport::JSON.decode(ActiveSupport::JSON.encode(Object.new))
=> {}
>> JSON.load(JSON.dump(Object.new))
=> "#<Object:0x000000012b61a068>"
```
If we were to select another default, I beleive it would need several
properties:
- It should only serialized a safe list of primitive types.
- It should explictly raise if attempting to serialize complex types.
YAML has quite a bit of footguns, as such it's desirable
to be able to substitute it for something else or even
simply to force users to define a serializer explictly for
every serialized columns.
