* Defaults: replace docker with containerd as our default container_manager
* CI: Use docker for download_localhost test
* Defaults: with container_manager=containerd we need etcd_deployment_type=host
* CI: Run weave jobs with docker
* CI: Vagrant don't download_force_cache
* CI: Fix upgrade tests
* should run compatible with old settings, this means docker
* we need to run with a distro that has at least modern containerd,
this means move from debian9 to debian10 to allow `containerd_version`
to match between 2.17 and master
* 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
