node-feature-discovery/pkg/nfd-gc/metrics.go
Markus Lehtonen 98c3b0750d nfd-gc: add metrics
Implements three metrics for nfd-gc:

- nfd_gc_build_info: version information of nfd-gc.
- nfd_gc_objects_deleted_total: total number of NodeFeature and
  NodeResourceTopology objects deleted by nfd-gc.
- nfd_gc_object_delete_failures_total: number of errors encountered when
  deleting NodeFeature and NodeResourceTopology objects.
