Describe the issue you're reporting

Sync the current naming of the allocatable metrics to the latest semconv introduced in open-telemetry/semantic-conventions#2267.

There should be a feature gate in place to handle the breaking change. The following metrics should be affected:

k8s.node.allocatable_cpu
k8s.node.allocatable_ephemeral_storage
k8s.node.allocatable_memory
k8s.node.allocatable_pods
