If the etcd cluster is separate and the etcd_deployment_type is "host",
there is no need for a container engine on the etcd nodes

Do not rely on a 'default(true)' filter, but define a proper default in
kubespray-defaults depending on etcd deployment method and if internal
or external etcd is used

* Add krew support

* Add reset for krew

* Update install krew(local)

* ansible lint

* yamllint

* fix krew default vars

* fix kubectl_localhost mode

* replace include

* fix e206

* rename ansible groups to use _ instead of -

k8s-cluster -> k8s_cluster
k8s-node -> k8s_node
calico-rr -> calico_rr
no-floating -> no_floating

Note: kube-node,k8s-cluster groups in upgrade CI
      need clean-up after v2.16 is tagged

* ensure old groups are mapped to the new ones

* Add nerdctl cli tool for containerd user

* Add nerdctl enable option

* Add nerdctl enable option and update nerdctl version to 0.8.0

Use kubeadm_feature_gates instead of kube_feature_gates to leverage kubeadm feature gates and not to interfere with k8s components feature gates (#7447)

* Set containerd version to 1.4.3

* Set containerd version to 1.4.4

* Allow connecting to bastion via non-standard port

* Fix bastion connection when ansible_port is not provided

This replaces kube-master with kube_control_plane because of [1]:

  The Kubernetes project is moving away from wording that is
  considered offensive. A new working group WG Naming was created
  to track this work, and the word "master" was declared as offensive.
  A proposal was formalized for replacing the word "master" with
  "control plane". This means it should be removed from source code,
  documentation, and user-facing configuration from Kubernetes and
  its sub-projects.

NOTE: The reason why this changes it to kube_control_plane not
      kube-control-plane is for valid group names on ansible.

* Move proxy_env to kubespray-defaults/defaults

There is no reasons to use set_facts here

* Ensure kubeadm doesn't use proxy

*_proxy variables might be present in the environment (/etc/environment, bash profile, ...)
When this is the case we end up with those proxy configuration in /etc/kubernetes/manifests/kube-*.yaml manifests

We cannot unset env variables, but kubeadm is nice enough to ignore empty vars
