NPD v0.7.0 release

Changes: v0.6.4...v0.7.0

NPD Metrics Support

In v0.7.0, @xueweiz added metrics support into NPD and made a major refactoring. The detailed design can be found in the proposal.

• System stats monitor. A system stats monitor is added into NPD as a new problem daemon. It collects useful node problem related system stats with OpenCensus such as disk/io_time, disk/weighted_io and disk/avg_queue_len.
• Problems as OpenCensus metrics. Besides node condition and events, problems detected by existing problem daemons are also collected into OpenCensus as metrics: problem_counter{reason="PROBLEM_REASON"} xxx for events and problem_gauge{reason="PROBLEM_REASON",type="PROBLEM_TYPE"} 1 or 0 for conditions.
• Prometheus endpoint. A Prometheus exporter is added to export all OpenCensus metrics collected by NPD through Prometheus.
• Plugin system for problem daemons. A plugin system for problem daemons is added. Problem daemons can be disabled at compile time with build tags, such as disable_system_stats_monitor, disable_system_log_monitor and disable_custom_plugin_monitor. New problem daemon plugins can be added in the future.
• Plugin system for problem exporters. A problem exporter interface is added. The original kubernetes problem reporting logic was moved into k8sexporter. Prometheus support is implemented as prometheusexporter. New problem exporters can be added in the future.
