* [etcd] ensure etcd is properly upgraded when managed by kubeadm

* [CI] add periodic job to test upgrade of etcd managed by kubeadm

* [ansible] make ansible 5.x the new default version and move different versions tested to nightly jobs

* [CI] jobs were missing proper ansible cleanup

* [calico] make vxlan encapsulation the default

* don't enable ipip encapsulation by default
* set calico_network_backend by default to vxlan
* update sample inventory and documentation

* [CI] pin default calico parameters for upgrade tests to ensure proper upgrade

* [CI] improve netchecker connectivity testing

* [CI] show logs for tests

* [calico] tweak task name

* [CI] Don't run the provisioner from vagrant since we run it in testcases_run.sh

* [CI] move kube-router tests to vagrant to avoid network connectivity issues during netchecker check

* service proxy mode still fails connectivity tests so keeping it manual mode

* [kube-router] account for containerd use-case

* CI: fix test name debian10-aio was a 2 instance default

* CI: Fix running ubuntu20-aio-docker

* CI: Fix running ubuntu18-aio-docker

* containerd: change default resolvconf_mode to host_resolvconf

* Wait for kube-apiserver to come back after pod refresh

* Handle resolv.conf gracefully

* Retain currently configured DNS entries to ensure we don't break the resolvers

* Suse uses wickedd for network management so no dhcp hooks

* Molecule: increase ansible timeout

* CI: Increase ansible timeout to 120s for Packet jobs

* Alpha-NodeSwap: allow nodes to use swap

* CI: Add Fedora 35 with experimental swap job

* Add Fedora 35 image, support and CI

* Cleanup tests and allow_failure for vagrant

* 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

* Reset: Fedora uses NetworkManager

* CI: test reset on fedora

* 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

* nodelocaldns: allow a secondary pod for nodelocaldns for local-HA

* CI: add job to test nodelocaldns secondary

* Sample-Inventory: add sample for calico_bpf_enabled

* Calico-Doc: note about CONFIG_NET_SCHED for eBPF support

* CI: Add Calico eBPF in HA mode test

* Fedora and RHEL use etc_t and the convention is <type_name>_t

* Docs: specify all values for preinstall_selinux_state

* CI: Add Fedora 34 with SELinux in enforcing mode

* Calico: add Wireguard support

* CI: Add Calico Wireguard scenario

* Update docker package to 20.10.6

* Add Fedora 33 image and CI, remove Fedora 31 (EOL)

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.
