Is it possible to return `key identifier` in the properties

[maxcc0]

Hi, is it possible to return key identifier in the props (so that one doesn't have to loop through the entities to get ti)?

e.g.

Kind = User Key Identifier=auto-generated Properties=name, email

Snippet:

 const query = datastore.createQuery('User')
 const [entities] = await datastore.runQuery(query)
 console.log(entities)

Expected sample response:

[{
id: <key identifier>
name: '',
email: ''
},
{
id: <key identifier>
name: '',
email: ''
}]
