Allow query schemes from Apollo tools to be imported

`persistgraphql` is being deprecated:

https://github.com/apollographql/persistgraphql/pull/67

I have replaced the extraction method with: https://github.com/apollographql/apollo-tooling

Upon extracting queries with this tool, the format is quite different:

```json
{
"version": 1,
"operations": [
{
"signature": "...",
"document": "...",
"metadata": {
"engineSignature": "..."
}
}
]
}
```

To avoid developers having to postprocess the data, it would be nice if the `GraphQL` module could support the upload of the manifest file.
