Hi,

we currently use `apollo-datasource-rest`, with which it’s possible to pass a `body` that is `FormData` as a second argument to the `post` method of a data source. That’s what we did for file uploads. But with `@apollo/datasource-rest` that’s not possible anymore.  
Looking at the source code of the `fetch` method of both packages, it seems like now everything that is not passing the following conditions (which are present in both) is being ignored:

```auto
    if (
      request.body !== undefined &&
      request.body !== null &&
      (request.body.constructor === Object ||
        Array.isArray(request.body) ||
        ((request.body as any).toJSON &&
          typeof (request.body as any).toJSON === 'function'))
    )

```

With `apollo-datasource-rest` a body which fell through that if statement was simply passed on as is. Does someone know what the reasoning behind this is? Maybe in the past we accidentally leveraged a “loophole” in the implementation?
