cb2e5ac776 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.

variable is registered.

  systemd limits due to the lack of consensus in the kernel community
  requires out-of-tree kernel patches.

f073ee91ea Copy hyperkube cni plugins optionally for calico deployment
Hyperkube from CoreOS now ships with all binaries required for
calico and flannel (but not weave). It simplifies deployment for
some network plugin scenarios to not download CNI images.

TODO: Optionally disable downloading calico to /opt/cni/bin

f94eb0b997 Support --ipip option for calico pool
Adds new boolean configuration variable for calico network plugin
`ipip`. When it's enabled calico pool is created with '--ipip'
option (IP-over-IP encapsulation across hosts).

Also refactor pool creation tasks to simplify logic and make tasks
more readable.
