Metrics with too much cardinality

[rev0lt]

Hi Team thanks for the great project, its very useful.
The following metrics are exposed with hosts label:
cloudflare_zone_requests_status_country_host
cloudflare_zone_firewall_events_count
cloudflare_zone_requests_origin_status_country_host

This hosts label has too much cardinality. Every request with a unique subdomain will end up on the hosts label with a unique timeseries which cant be controlled on our end. We presently use relabel_configs to remove those metrics before ingestion. But i would very much appreciate if we can get the same metrics aggregated to a zone without the hosts label. Thanks again.
