When scraping stackdriver, it can return quite a lot of data, and sometimes can be slow.
In order to improve scrape speed and reliability, you need to reduce the number of type prefixes.
Currently you can shard the exporter, which works well enough.
Another way to do this is to have a collect[] URL param that allows the user to split up the data more dynamically without having to deploy multiple exporters. This is possible in exporters like the mysqld_exporter and node_exporter.
