AdditionalProperties behavior differences

[yishanhe]

I am not sure if these two should be different?

definitions

    Foo:
      type: object
      additionalProperties: true

    Bar:
      type: object
      additionalProperties:
        type: object

code generated

// Foo defines model for Foo.
type Foo struct {
	AdditionalProperties map[string]interface{} `json:"-"`
}

// Bar defines model for Bar.
type Bar struct {
	AdditionalProperties map[string]map[string]interface{} `json:"-"`
}

Should Bar also be generated as Foo here? Thanks.
