When `BuildConfigFromFlags(apiserver, kubeconfig)` was called with empty apiserver and kubeconfig, it fallback to rest.InClusterConfig(). When it happened, amazon-k8s-agent outputs following warning message. ``` ERROR: logging before flag.Parse: W1217 10:37:25.707719 13 client_config.go:533] Neither --kubeconfig nor --master was specified. Using the inClusterConfig. This might not work. ``` Although this error is harmless, it causes some confusion. This patch changes to use `InClusterConfig()` when `BuildConfigFromFlags` was called with empty args. P.S `logging before flag.Parse` is also gone by this patch, as glog is not called.
