[Query] Set max-results to 10.000 by default

This PR fixes a "bug" in the `Query` about default `max-results` value. The value was 1.000 but according to the [spec](https://developers.google.com/analytics/devguides/reporting/core/v3/reference#maxResults), 1.000 is the default value if you don't provide a value. The Google Analytics service can return a maximum of 10.000 rows, so, I use now this value as default value.

IMO, the bundle should try (by default) to reduce the number of request done when we fetch a big dataset without having to take care about the `max-results`. Without this fix, it is not the case...
Additionally, if devs use the current version to fetch a big dataset through a loop & without set the `max-results` explictly, I really recommend them to upgrade in order to reduce the number of request done.
