codebase have been updated with the new endpoint.

Based on the discussion here: https://github.com/kubernetes/kubernetes/pull/97415#discussion_r722548437
we explictly state that the GetCpuIds returned for a ContainerResource in the ListPodResourcesResponse
represent only exclusively allocated CPUs.
In order to evaluate the CPUs corresponding to the shared pool, List endpoint should be used in conjunction
with GetAllocatableResources endpoint. We highlight the steps that the client needs to take evaluate this.

Also, explicitly clarify the behavior of GetAllocatableResources
The explanation that GetAllocatableResources can be used to obtain available resources
on the node can be misinterpretted as an API that is used to obtain free/unallocated
resources on a node.
This PR adds additional text to clarify that this API endpoint only returns
allocatable resources which are resources exposed to kubelet as defined here:
https://kubernetes.io/docs/tasks/administer-cluster/reserve-compute-resources/#node-allocatable.

The `/var/lib/kubelet/pod-resources/kubelet.sock` is required by device monitoring agent but not device plugin.
This word `plugin` is ambiguous.
plugin -> device monitoring agent
