Subject: [PATCH 1/5] Make Adapters registerable so they are not
 namespace-constrained

Changes:

- Introduce Adapter::get for use by Serializer.adapter
- Move Adapter-finding logic from Adapter::adapter_class into Adapter::get

Introduced interfaces:

- non-inherited methods
```ruby
ActiveModel::Serializer::Adapter.adapter_map     # a Hash<adapter_name, adapter_class>
ActiveModel::Serializer::Adapter.adapters        # an Array<adapter_name>
ActiveModel::Serializer::Adapter.register(name, klass) # adds an adapter to the adapter_map
ActiveModel::Serializer::Adapter.get(name_or_klass)    # raises Argument error when adapter not found
```

- Automatically register adapters when subclassing

```ruby
      def self.inherited(subclass)
        ActiveModel::Serializer::Adapter.register(subclass.to_s.demodulize, subclass)
      end
```

- Preserves subclass method `::adapter_class(adapter)`

```ruby
      def self.adapter_class(adapter)
        ActiveModel::Serializer::Adapter.get(adapter)
      end
```

- Serializer.adapter now uses `Adapter.get(config.adapter)` rather than have duplicate logic

+If you want to have a root key for each resource in your responses, you should use the Json or
+JsonApi adapters instead of the default FlattenJson:
 
 ```ruby
 ActiveModel::Serializer.config.adapter = :json
 ```
+
+## Advanced adapter configuration
+
+### Registering an adapter
+
+The default adapter can be configured, as above, to use any class given to it.
+
+An adapter may also be specified, e.g. when rendering, as a class or as a symbol.
+If a symbol, then the adapter must be, e.g. `:great_example`,
+`ActiveModel::Serializer::Adapter::GreatExample`, or registered.
+
+There are two ways to register an adapter:
+
+1) The simplest, is to subclass `ActiveModel::Serializer::Adapter`, e.g. the below will
+register the `Example::UsefulAdapter` as `:useful_adapter`.
+
+```ruby
+module Example
+  class UsefulAdapter < ActiveModel::Serializer::Adapter
+  end
+end
+```
+
+You'll notice that the name it registers is the class name underscored, not the full namespace.
+
+Under the covers, when the `ActiveModel::Serializer::Adapter` is subclassed, it registers
+the subclass as `register(:useful_adapter, Example::UsefulAdapter)`
+
+2) Any class can be registered as an adapter by calling `register` directly on the
+`ActiveModel::Serializer::Adapter` class. e.g., the below registers `MyAdapter` as
+`:special_adapter`.
+
+```ruby
+class MyAdapter; end
+ActiveModel::Serializer::Adapter.register(:special_adapter, MyAdapter)
+```
+
+### Looking up an adapter
+
+| `ActiveModel::Serializer::Adapter.adapter_map` | A Hash of all known adapters { adapter_name => adapter_class } |
+| `ActiveModel::Serializer::Adapter.adapters`    | A (sorted) Array of all known adapter_names |
+| `ActiveModel::Serializer::Adapter.get(name_or_klass)` |  The adapter_class, else raises an `ActiveModel::Serializer::Adapter::UnknownAdapter` error |
+| `ActiveModel::Serializer::Adapter.adapter_class(adapter)` | delegates to `ActiveModel::Serializer::Adapter.get(adapter)` |
+| `ActiveModel::Serializer.adapter` | a convenience method for `ActiveModel::Serializer::Adapter.get(config.adapter)` |
+
+The registered adapter name is always a String, but may be looked up as a Symbol or String.
+Helpfully, the Symbol or String is underscored, so that `get(:my_adapter)` and `get("MyAdapter")`
+may both be used.
+

Subject: [PATCH 2/5] Ensure inheritance hooks run

I was seeing transient failures where adapters may not be registered.

e.g. https://travis-ci.org/rails-api/active_model_serializers/builds/77735382

Since we're using the Adapter, JsonApi, and Json classes
as namespaces, some of the conventions we use for modules don't apply.
Basically, we don't want to define the class anywhere besides itself.
Otherwise, the inherited hooks may not run, and some adapters may not
be registered.

For example:

If we have a class Api `class Api; end`
And Api is also used as a namespace for `Api::Product`
And the classes are defined in different files.

In one file:

```ruby
class Api
  autoload :Product
  def self.inherited(subclass)
    puts
    p [:inherited, subclass.name]
    puts
  end
end
```

And in another:

```ruby
class Api
  class Product < Api
    def sell_sell_sell!
      # TODO: sell
    end
  end
end
```

If we load the Api class file first, the inherited hook will be defined on the class
so that when we load the Api::Product class, we'll see the output:

```plain
[ :inherited, Api::Product]
```

However, if we load the Api::Product class first, since it defines the `Api` class
and then inherited from it, the Api file was never loaded, the hook never defined,
and thus never run.

By defining the class as `class Api::Product < Api` We ensure the the Api class
MUST be defined, and thus, the hook will be defined and run and so sunshine and unicorns.

Appendix:

The below would work, but triggers a circular reference warning.
It's also not recommended to mix require with autoload.

```ruby
require 'api'
class Api
  class Product < Api
    def sell_sell_sell!
      # TODO: sell
    end
  end
end
```

This failure scenario was introduced by removing the circular reference warnings in
https://github.com/rails-api/active_model_serializers/pull/1067

Style note:

To make diffs on the adapters smalleer and easier to read, I've maintained the same
identention that was in the original file.  I've decided to prefer ease of reading
the diff over style, esp. since we may later return to the preferred class declaration style.

 with '#' will be ignored, and an empty message aborts the commit.

Subject: [PATCH 3/5] Rename Adapter.get to Adapter.lookup

Per https://github.com/rails-api/active_model_serializers/pull/1017#discussion_r39003855
comment by sandstrom in discussion of the inherited hook

> I'm thinking that it would be better to register adapters manually, without using the hook, i.e.
> have people call ActiveModel::Serializer::Adapter.register directly (perhaps in an initializer).

> Possibly, some inspiration can be taken from how ActiveJob adapters are wired[1].

> [1] https://github.com/rails/rails/blob/a11571cec3213753d63ac3e6b4bb3b97fe2594a6/activejob/lib/active_job/queue_adapter.rb#L52-L56

 The registered adapter name is always a String, but may be looked up as a Symbol or String.
 Helpfully, the Symbol or String is underscored, so that `get(:my_adapter)` and `get("MyAdapter")`
