Failed to create kubernetes client: invalid configurations: no configuration has been provided

[npattanayak]

For clusters hosted on aws , for which we do not want to give access to the kube config file in the root directory, we can get the configurations from "/var/run/secrets/kubernetes.io/serviceaccount/token" . We can thus use a flag which allows us to turn off privileged access and thereby gets cluster config from rest.InClusterConfig() in Clientcmd.BuildConfigFromFlags
