ea1f072c7e Granular authentication Control
It is now possible to deactivate selected authentication methods
(basic auth, token auth) inside the cluster by adding
removing the required arguments to the Kube API Server and generating
the secrets accordingly.

The x509 authentification is currently not optional because disabling it
would affect the kubectl clients deployed on the master nodes.

Cesarini, Daniele
d7f5fdc0c5 Adding /O=system:masters to admin certificate
Issue #1125. Make RBAC authorization plugin work out of the box.
"When bootstrapping, superuser credentials should include the system:masters group, for example by creating a client cert with /O=system:masters. This gives those credentials full access to the API and allows an admin to then set up bindings for other users."

fff8780a51 set "check_mode: no" for read-only "shell" steps that registers result
"shell" step doesn't support check mode, which currently leads to failures,
when Ansible is being run in check mode (because Ansible doesn't run command,
assuming that command might have effect, and no "rc" or "output" is registered).

Setting "check_mode: no" allows to run those "shell" commands in check mode
(which is safe, because those shell commands doesn't have side effects).

48e77cd8bb 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.

707e6a4642 This PR adds/or modifies a few tasks to allow for the playbook to
be run by limit on each node without regard for order.

The changes make sure that all of the directories needed to do
certificate management are on the master[0] or etcd[0] node regardless
of when the playbook gets run on each node.  This allows for separate
ansible playbook runs in parallel that don't have to be synchronized.

04fbe42aa6 If the inventory name of the host exceeds 63 characters,
the openssl tools will fail to create signing requests because
the CN is too long.  This is mainly a problem when FQDNs are used
in the inventory file.

THis will truncate the hostname for the CN field only at the
first dot.  This should handle the issue for most cases.
