Framework for implementing custom metrics support for Kubernetes
A release process following Kubernetes releases was added to the project. The major and minor versions of custom-metrics-apiserver are in sync with upstream Kubernetes and the patch version is reserved for changes in custom-metrics-apiserver that we want to release without having to wait for the next version of Kubernetes.
Since the project is in sync with upstream Kubernetes releases, it is following the same support policies, so alongside this release will be cut two other releases (v1.19, v1.20) to have the three most recent releases of Kubernetes.
