* Fixes various issues in vSphere Terraform code
Provided to address various shortcomings and to fix the following
issue in upstream Kubespray:
https://github.com/kubernetes-sigs/kubespray/issues/8176
* Resolves Terraform formatting issues
* Sets default prefix to human-readable name
* Documents new default prefix in README
* Ansible: separate requirements files for supported ansible versions
* Ansible: allow using ansible 2.11
* CI: Exercise Ansible 2.9 and Ansible 2.11 in a basic AIO CI job
* CI: Allow running a reset test outside of idempotency tests and running it in stage1
* CI: move ubuntu18-calico-aio job to stage2 and relay only on ubuntu20 with the variously supported ansible versions for stage1
* CI: add capability to install collections or roles from ansible-galaxy to mitigate missing behavior in older ansible versions
* Kata-containes: Fix for ubuntu and centos sometimes kata containers fail to start because of access errors to /dev/vhost-vsock and /dev/vhost-net
* Kata-containers: use similar testing strategy as gvisor
* Kata-Containers: adjust values for 2.2.0 defaults
Make CI tests actually pass
* Kata-Containers: bump to 2.2.2 to fix sandbox_cgroup_only issue
* Limit kubectl delete node to k8s nodes
This avoids the use of `kubectl delete node` when removing etcd nodes
which are not part of the cluser (separate etcd)
* Take errors into account when deleting node
There should not be error now that we're limiting the deletion to nodes
actually in the cluster
* Retrying on error
* 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
* nginx-ingress: bump to 1.0.4
* Disable builtin ssl_session_cache solving the problem with OpenSSL consuming memory.
* Print warning only instead of error if no IngressClass permission is available.
* nginx-ingress: bump to 1.0.4 in the README
* Disable builtin ssl_session_cache solving the problem with OpenSSL consuming memory.
* Print warning only instead of error if no IngressClass permission is available.
* Containerd: download containerd from upstream instead of using distro specific packages
split runc download to separate role
make bootstrap-os role deploy container-selinux and seccomp libraries
clean up package manager provided containerd
move variables to docker role that are no longer common with containerd
* Containerd: make molecule testing more relevant
* replace ubuntu18 with ubuntu20
* add centos8 and debian11 to molecule tests
* run kubernetes/preinstall role to ensure relevancy
of test including dependency packages
* CI: adjust test scenarios for downloaded containerd
