What type of PR is this?
/kind feature

What this PR does / why we need it:
This introduces a new kubelet socket, which provides read-only information about pods, and serves a grpc service. The initial use-case for this is to support out-of-tree monitoring agents, which need to be able to correlate devices and containers.

Which issue(s) this PR fixes:
Feature Issue: kubernetes/enhancements#606
KEP: kubernetes/community#2454

Special notes for your reviewer:
The API is in pkg/kubelet/apis/podresources/v1alpha1.
This adds to the device plugin e2e_node test to test its functionality.

Add a kubelet socket which serves an grpc service containing the devices used by containers on the node.

add kubelet client for Pod resource info
6708bed 
This change introduces kubelt client to get allocated device
information of a Pod from newly added Kubelet grpc service.
For more information please see:
kubernetes/kubernetes#70508

With this kubelet service we no longer need to rely on kubelet
checkpoint file to get device information.
