Hi.
I'm using MongoDB and sails-mongo v2.0.0.

According to https://sailsjs.com/documentation/concepts/models-and-orm/model-settings#?schema, not-defined attribute(arbitrary data) can be allowed if `config.models.schema` is set to false.
But, I failed to do that with the below message when creating a record to a model:
```
WARNING: Automatically trimmed extraneous values!
In call to addMyModel(), 1 of the provided values (notDefinedAttribute) does not correspond with any recognized input.
Please try again without the extra value, or check your usage and adjust accordingly.
```

In addition, controllers also remove not-defined attributes when it is called thru routes.

How can I allow it?

Start with the documented config.models.schema setting and reproduce the warning from addMyModel() using an undefined attribute. Then trace the controller path when the model is called through routes. Done means identifying why the attribute is trimmed and documenting or verifying the configuration needed to preserve it.
