PodResources client could be used by sriov cni to obtain devices
allocated for container by sriov device-plugin.
KubeletPodResources service is still in alpha, so it should be
explicitly enabled in kubelet feature-gates:
kubelet --feature-gates KubeletPodResources=true
New config option 'kubelet_root_dir' added to 'sriov' section
that defaults to kubelet default root-dir '/var/lib/kulelet'.
In case kubelet started with non-default root directory passed
via '--root-dir' option, the same value should be configured
in 'kubelet_root_dir'.
Note that if sriov binding driver will be used inside container
'kubelet_root_dir'/pod-resources directory should be mounted
to this container in order to allow communication with kubelet
via gRPC protocol over the unix domain socket.
