1.0.0:
Breaking changes
The netdev collector CLI argument --collector.netdev.ignored-devices was renamed to --collector.netdev.device-blacklist in order to conform with the systemd collector.
The label named state on node_systemd_service_restart_total metrics was changed to name to better describe the metric.
Refactoring of the mdadm collector changes several metrics
node_md_disks_active is removed
node_md_disks now has a state label for "failed", "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.
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.
Collectors that are enabled, but are unable to find data to collect, now return 0 for node_scrape_collector_success.
