Urgent Upgrade Notes

HTTP serving logic for the metrics manager has been refactored.
- Sidecars should create an HTTP mux (e.g. http.ServeMux) and pass it into RegisterToServer().
- Sidecars are responsible for starting a server with this mux. (#70, @verult)

Feature

Added leader election health check.
- Sidecars should create an HTTP mux (e.g. http.ServeMux) and pass it into RegisterHealthCheck().
- Sidecars are responsible for starting a server with this mux.
- A liveness probe has to be added to the pod spec for the sidecar container. (#70, @verult)

Bug or Regression

Workaround issue of process_start_time metric not showing up. (#68, @Jiawei0227)
Process_start_time should be unique in a process and therefore can now be disabled in the metrics manager registry if not needed or when it conflicts with other collectors (#67, @pohly)

Other (Cleanup or Flake)

Projects using csi-lib-utils should update to klog/v2 or must ensure that klog/v1 and klog/v2 are both configured as described in https://github.com/kubernetes/klog/blob/master/examples/coexist_klog_v1_and_v2/coexist_klog_v1_and_v2.go. (#60, @pohly)
