The `assert_serializer` test helper was added in 0.9.0.apha1[1],
and was not included in 0.10.
This patch brings back the `assert_serializer` test helper. This is the last
revision[2] that has the helper. The original helper was used as base.

- Create the AssertSerializer
- Use the Test namespace
- Make the tests pass on the Rails master
- Rails 5 does not include `assert_template` but we need this on the tests of
the helper.
- This add the `rails-controller-testing` to keep support on `assert_template`.
- Only load test helpers in the test environment
For discussion:
Consider evaluating association in serializer context
That way, associations are really just anything that
can be conditionally included. They no longer
have to actually be methods on the object or serializer.
e.g.
```diff
has_many :comments do
- last(1)
+ Comment.active.for_serialization(object).last(1)
end
```
It's an upgrade based on the new Cache implementation #693.
It allows to use the Rails conventions to cache
specific attributes or associations.
It's based on the Cache Composition implementation.
In some cases, we want to pass arguments from the controller and we want
to serializer a resource according to that. This allows serializers to
use the `options` method to retrieve whatever was passed in via
arguments.
It's a new implementation of cache based on ActiveSupport::Cache.
The implementation abstracts the cache in Adapter class on a
private method called cached_object, this method is intended
to be used on Adapters inside serializable_hash method in order
to cache each instance of the object that will be returned by
the serializer.
Some of its features are:
- A different syntax. (no longer need the cache_key method).
- An options argument that have the same arguments of ActiveSupport::Cache::Store, plus a key option that will be the prefix of the object cache on a pattern "#{key}-#{object.id}".
- It cache the objects individually and not the whole Serializer return, re-using it in different requests (as a show and a index method for example.)
