When running ansible-lint directly, we can see a lot of warning
message like
risky-file-permissions File permissions unset or incorrect
This fixes the warning messages.
* Ensure addon-resizer 1.8.11 only effective at arch amd64.
k8s.gcr.io/addon-resizer:1.8.11 returns the amd64 image which is not executable at arm64.
Disable addon-resizer when the platform is not amd64.
When metrics-server upgrade and use addon-resizer:2.3, then revert this
commit and `image_arch` will determine the `addon_resizer_image_tag`.
* Add metrics_server_resizer architectures check
The addon-resizer container can reduce resource limits of cpu and
memory of metrics-server container in the pod, and that caused
OOMKilled.
In addition, the original metrics-server manifest doesn't contain
the addon-resizer container as [1].
So this adds metrics_server_resizer option to control the addon-resizer
container deployment and the default value is false to make it stable
for most environments.

"allowPrivilegeEscalation: false" blocks deploying metrics-server
on CentOS7. In addition, the original metrics-server manifest doesn't
contain it as [1]. This removes it.

* 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
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.
