Features and Enhancements

• Update to kubernetes v1.14.1 - Upgraded from Kubernetes v1.13.5 [changelog]. This Kubernetes upgrade moves pid limiting to beta and is enabled by default, which may not be supported by all kernels.

   --kube-apiserver-arg value          Customized flag for kube-apiserver process
   --kube-scheduler-arg value          Customized flag for kube-scheduler process
   --kube-controller-arg value         Customized flag for kube-controller-manager process
   --kubelet-arg value                 (agent) Customized flag for kubelet process
   --kube-proxy-arg value              (agent) Customized flag for kube-proxy process

• Initial metrics-server support [#252] - Configures aggregation layer so metrics server can be launched and metrics scraped. Future enhancements will remove need for a custom metrics server deployment.
