Kubernetes.container.cpu.usage.node.pct reports capacity rather than documented allocatable usage

Before opening a Bug, opening this issue as requested.

According to the docs here:

The kubernetes.container.cpu.usage.node.pct and kubernetes.container.memory.usage.node.pct are supposed to report the node allocatable usage percentages, however they actually report node capacity percentages.

The relevant code is here:

Indeed changing the the code from "Capacity" to "Allocatable" in the line above fixes the problem. I notice the Memory usage calculation is also likewise incorrect on line 632 of the above source.

Can this be fixed please?
