Problem setting dataloader contextToOptions with dataloader-sequelize 2.0.0

[caioflores]

Following this discussion: https://github.com/mickhansen/graphql-sequelize/issues/656

The example server of dataloader with graph-yoga is not working anymore with dataloader-sequelize 2.0.0: https://github.com/mickhansen/graphql-sequelize/blob/master/examples/graphql-yoga/src/server.js

The new way to make it work as @intellix solved is:

schema.context = req => {
  const dataloaderContext = createContext(sequelize);

  resolver.contextToOptions = {
    dataloaderContext: [EXPECTED_OPTIONS_KEY]
  };
  return {
    ...req,
    dataloaderContext
  };
};

I'll open a PR to update README and example.
