feat(add dataloader options)

[mattkrick]

you can now pass in dataLoaderOptions via context.

example:

const resolveEndpointContext = () => {
  return {dataLoaderOptions: {maxBatchSize: 1}}

this will limit a batch size to 1, which means every request will get sent on its own.
you can come up with a better strategy & employ that. see https://github.com/graphql/dataloader#batch-scheduling
