Feature request: history of an entity

[cag]

Right now, a query like this is possible already if I want to see how changingField changes on a thing:

{
  b6149422: thing(
    id: "1",
    block: {
      number: 6149422
    }
  ) {
    changingField
  }
  b6149423: thing(
    id: "1",
    block: {
      number: 6149423
    }
  ) {
    changingField
  }
  # ...
}

However, this isn't scalable to a week's worth of time, which would take 40k entries, and could be about a value that changes seldomly.

This feature is about making a way to get the sparse history of an entity with pagination and within a block range.
