Pending disk operations metric

What's missing?

A metric defined in semconv for capturing pending disk operations for which there is one in https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/main/receiver/hostmetricsreceiver/internal/scraper/diskscraper/documentation.md

Describe the solution you'd like

A new metric defined which complementssystem.disk.operations.

Perhaps we rename that metric to system.disk.operation.completed and the new one can be system.disk.operation.queded.

This would also enable system.disk.operation_time to become system.disk.operation.time or system.disk.operation.duration.
