Node feature discovery for Kubernetes
250aea4741
Add support for management of Extended Resources via the NodeFeatureRule CRD API. There are usage scenarios where users want to advertise features as extended resources instead of labels (or annotations). This patch enables the discovery of extended resources, via annotation and patch of node.status.capacity and node.status.allocatable. By using the NodeFeatureRule API.
