Pagination model

I think it might be nice to have a pagination model that will allow to create universal resolvers, types definitions, etc. for collections.

For now I am going to expose two types of models:

Simple pagination

Like with standard rest apis - only offset (skip), limit (take), count and items.

@Resolver()
class SampleResolver {
  @Query(returns => [Type])
  paginatedQuery(
    @PaginationArgs() { offset, limit }: PaginationArgs,
  ): PaginationResponse<Type> {
    // ...
    return [data, count];
  }
}

By using @PaginationArgs() it will detect that the query is being paginated, so the returned tuple [TData, number] will be converted into an object with page info (hasNextPage, etc.), data and total properties.

Relay connection

Using cursor model, which is better for highly dynamic collections:

API - TBD.
