Title: Read default serializer options from the controller

This allows you to do something like:

```
helper do
def default_serializer_options
{only: params[:only], except: params[:except]}
end
end
```

And then on any route you could fetch only fields you actually need. There are many other use-cases of course, but this was my main motivation.
