The current `List()` implementation just lists the DNS resorce records in a given managed zone once and retruns the list. It neither performs a paged walk nor does it consider the `page_token` in the returned response. This change walks all the pages and aggregates the records in the pages and returns the aggregated list. This is potentially dangerous as it can blow up memory if there are a huge number of records in the given managed zone. But this is the best we can do without changing the provider interface too much. Next step is to define a new paged list interface and implement it.
