Improvement in function parameters

It would be more interesting if instead of having fixed order parameters, an object is used for the parameters in the functions createScalarField, createObjectField, createDataSource. An article to use as a reference: [The Options Object Pattern with TypeScript](https://medium.com/@bchadwickfrance/the-options-object-pattern-with-typescript-a14f33306ec8).

Example implementation:
`createDataSource({ name: string, provider: DataSourceProvider, url: string | DataSourceURLEnv }): DataSource`
