- docs/sd_configs.md: moved hetzner_sd_configs docs to the correct place according to alphabetical order of SD names, document missing __meta_hetzner_role label. - lib/promscrape/config.go: added missing MustStop() call for Hetzner SD, and moved the code to the correct place according to alphabetical order of SD names. - lib/promscrape/discovery/hetzner: properly handle pagination for hloud API responses, populate missing __meta_hetzner_role label like Prometheus does. - Properly populate __meta_hetzner_public_ipv6_network label like Prometheus does. - Remove unused SDConfig.Token. - Remove "omitempty" annotation from SDConfig.Role field, since this field is mandatory.
