What type of PR is this?

/kind feature

What this PR does / why we need it:
This PR changes our default container_manager to containerd. This brings in more flexibility with the default out of the box experience since with containerd we can enable extra container runtimes like kata containers or gvisor and allows us to clean some legacy code in the CI.
I added specific jobs for docker on ubuntu18, ubuntu20, centos8, debian10 and debian11 to ensure we don't accidentally break docker support.

Which issue(s) this PR fixes:

Fixes #7985

Special notes for your reviewer:

Does this PR introduce a user-facing change?:

I think this PR is now in good shape.

The 3 CI failures are like this:

  1. https://gitlab.com/kargo-ci/kubernetes-sigs-kubespray/-/jobs/1804745627 - debian9-macvlan - this needs some investigation
  2. https://gitlab.com/kargo-ci/kubernetes-sigs-kubespray/-/jobs/1804750376 - oel7 fix pending in OEL7: Fix CentOS7 Extras for OEL7 #8219
  3. https://gitlab.com/kargo-ci/kubernetes-sigs-kubespray/-/jobs/1804749484 - ubuntu16-weave (docker) needs pinned down containerd version

I would prefer to fix 1 and 3 in separate PRs.

/cc @floryut @oomichi @champtar what do you think?

I totally agree, big pr like that can't really be done in one shot otherwise it take way too much time and require a lot of works.

So fine by me to merge this as is and move forward with it 👍 great work there @cristicalin

Having etcd_kubeadm_enabled set to false and etcd_deployment_type to host by default is a big setback for me.

Having etcd_kubeadm_enabled set to false and etcd_deployment_type to host by default is a big step back for me.

Hum, this PR doesn't change etcd_kubeadm_enabled default 🤔
But indeed as the PR switch the container runtime to containerd by default, we can't keep etcd_deployment_type to docker otherwise the default setting for kubespray wouldn't work

I contemplated switching etcd_kubeadm_enabled to true by default but it seems like changing unrelated settings, it would probably make sense to rework the scope of this variable to etcd_deployment_type: kubeadm.

For this PR I think it makes sense to keep the change as proposed and rework the duplicate variable meanings. And change the default after to rely on kubeadm.

ok let's switch container runtime to containerd to get rid of docker dependency, it's worth it.
But let's make etcd deployment use kubeadm by default in another PR
