This follows the pattern `kubectl` uses for logging.
There are two remaining glog.Infof call that cannot be removed easily.
One glog call comes from kubelet validation which calls features.SetFromMap.
The other comes from test/e2e during kernel validation.

Implement and use loadPodSpecFromFile which loads and returns PodSpec object
from YAML or JSON file. Use this function in the places where LoadPodFromFile
is used to load Pod object and then return the PodSpec portion of it. This
also removes the dependency on //pkg/volume/util and its dependencies (thus,
making kubeadm more lean).
