Manual fragment spreads

[rpiaggio]

Grackle now requires manually resolving fragment spreads.

Not sure whhat fragments are but LGTM

fragment fooFields on Foo {
  id
  name
}

query {
  foo {
    ...fooFields
  }
}

The old grackle parser would solve the fragment and provide us with id and name inside foo in the main query. Now it provides the jigsaw pieces and we have to assemble it ourselves.
