Kubernetes Dual-Stack Runtime Configuration
New classes and scripts are added to handle sm, kubelet, kubeadm, kube-proxy, calico, multus, and certsans. New variables exported to the hiera are used in this change, in conjunction with the existing ones: platform::kubernetes::params::node_ip_secondary platform::network::cluster_pod::params::* platform::network::cluster_pod::ipv4::params:: platform::network::cluster_pod::ipv6::params::* platform::network::cluster_service::params::* platform::network::cluster_service::ipv4::params:: platform::network::cluster_service::ipv6::params::* Test Plan: ========== In all tests pods were brought up and the datapath was validated directly and through a service [PASS] in AIO-DX IPv4, configure dual-stack and back to single-stack [PASS] in AIO-DX IPv6, configure dual-stack and back to single-stack [PASS] in AIO-SX IPv4, configure dual-stack and back to single-stack [PASS] in AIO-SX IPv6, configure dual-stack and back to single-stack [PASS] in Standard IPv4, configure dual-stack and back to single-stack [PASS] in Standard IPv6, configure dual-stack and back to single-stack Story: 2011027 Task: 50203 Change-Id: Ifb908c097960f90c5eabeca8cc02d2f60ae4d731 Signed-off-by: Andre Kantek <andrefernandozanella.kantek@windriver.com>
