Drop linux capabilities and rework users/groups * Drop linux capabilities for unprivileged containerized worlkoads Kargo configures for deployments. * Configure required securityContext/user/group/groups for kube components' static manifests, etcd, calico-rr and k8s apps, like dnsmasq daemonset. * Rework cloud-init (etcd) users creation for CoreOS. * Fix nologin paths, adjust defaults for addusers role and ensure supplementary groups membership added for users. * Add netplug user for network plugins (yet unused by privileged networking containers though). * Grant the kube and netplug users read access for etcd certs via the etcd certs group. * Grant group read access to kube certs via the kube cert group. * Remove priveleged mode for calico-rr and run it under its uid/gid and supplementary etcd_cert group. * Adjust docs. * Align cpu/memory limits and dropped caps with added rkt support for control plane.
