By default Calico CNI does not create any network access policies
or profiles if 'policy' is enabled in CNI config. And without any
policies/profiles network access to/from PODs is blocked.

K8s related policies are created by calico-policy-controller in
such case. So we need to start it as soon as possible, before any
real workloads.

This patch also fixes kube-api port in calico-policy-controller
yaml template.

Migrate k8s data to etcd3 api store

Closes: #1135
Closes: #1026
Signed-off-by: Sergii Golovatiuk <sgolovatiuk@mirantis.com>

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.

Explicitly set cni-bin-dir

Default backend is now etcd3 (was etcd2).
The migration process consists of the following steps:
* check if migration is necessary
* stop etcd on first etcd server
* run migration script
* start etcd on first etcd server
* stop kube-apiserver until configuration is updated
* update kube-apiserver
* purge old etcdv2 data

Upgraded nodes do not obtain labels automatically.
See https://github.com/kubernetes/kubernetes/pull/29459 for more details.

To use OpenID Connect Authentication beside deploying an OpenID Connect
Identity Provider it is necesarry to pass additional arguments to the Kube API Server.
These required arguments were added to the kube apiserver manifest.

Disable vault role properly on ansible 2.2.0

Remove standalone etcd specific play, cleanup host mode

Now etcd role can optionally disable etcd cluster setup for faster
deployment when it is combined with etcd role.

Use find module for checking for certificates

Added Missing AWS IAM Profiles and Policies

The AWS IAM profiles and policies required to run Kargo on AWS
are no longer hosted in the kubernetes main repo since kube-up got
deprecated. Hence we have to move the files into the kargo repository.
