mutations should use the same key for data in outer and inner tables

[tirumaraiselvan]

Currently, we use objects for outer table and data for inner table:

mutation insert_article {
  insert_article(
    objects: [
      {
        id: 21,
        title: "Article 1",
        content: "Sample article content",
        author: {
          data: {
            id: 11,
            name: "Cory"
          }
        }
      }
    ]
  ) {
    affected_rows
    returning {
      id
      title
      author {
        id
        name
      }
    }
  }
}

Possible options:

1. Use objects in both
2. Use data in both
3. Use objects or object based on relationship type

I vote for no. 3. Objects or object in upsert makes more sense.

Also, will this be a breaking change? @0x777
