What this PR does / why we need it:

Users requested that all kubernetes-csi sidecars serve leader, work queue, process, and Go runtime metrics via Kubernetes legacymetrics. These metrics are only served by external-provisioner today due to kubernetes-csi/external-provisioner#579.

We recently updated csi-lib-utils to serve additional registries via PR kubernetes-csi/csi-lib-utils#189.

This PR ensures this sidecar serves those additional metrics.

Testing:

• See that new metrics were added via this gist: https://gist.github.com/AndrewSirenko/2d3bcd1cbc47541cab4f4fae9561fec0
• Built all sidecar, deployed alongside EBS CSI Driver v1.40. Saw new metrics when scraping each sidecar /metrics endpoint.
• Also tested upgrade case: No errors when upgrading EBS CSI Driver via helm from revision with default sidecars to these custom sidecars.
• Excercised dynamic provisioning, snapshot, resize, and modify workflows. No errors. Workqueue metrics increased.
