Add where args to GQL query

[onn-software]

We should extend the GQL schema to support a where clause. In the schema generator we could add a __WHERE_TYPE__ and make it an type that shares the same keys are type, and takes in arrays of it's value type. This we can use in the sql where clause.

${key}(paginate: Paginate, where: __WHERE_TYPE__): Paginated${type}
