Mongo ObjectId fields issue

[ngdbao]

While _id is not only ObjectId field in most collection, any other objectId may cause below error:

TypeError: Object of type ObjectId is not JSON serializable

So, It would be better if we can define stringify some fields right in config.yml, example like this:

  - table: picture
    index: beauty-pictures
    full: true
    fields:
      id: str(id)
      uid: str(id)
      description: description
      category: category
