Release 1.0.0

* The netdev collector CLI argument `--collector.netdev.ignored-devices` was renamed to `--collector.netdev.device-blacklist` in order to conform with the systemd collector. #1279
* The label named `state` on `node_systemd_service_restart_total` metrics was changed to `name` to better describe the metric. #1393
* Refactoring of the mdadm collector changes several metrics
    - `node_md_disks_active` is removed
    - `node_md_disks` now has a `state` label for "fail", "spare", "active" disks.
    - `node_md_is_active` is replaced by `node_md_state` with a state set of "active", "inactive", "recovering", "resync".
* Additional label `mountaddr` added to NFS device metrics to distinguish mounts from the same URL, but different IP addresses. #1417
* Metrics node_cpu_scaling_frequency_min_hrts and node_cpu_scaling_frequency_max_hrts of the cpufreq collector were renamed to node_cpu_scaling_frequency_min_hertz and node_cpu_scaling_frequency_max_hertz. #1510
* Collectors that are enabled, but are unable to find data to collect, now return 0 for `node_scrape_collector_success`.
