* Drop CI jobs related to canal

According to the canal github[1] the repo is not maintained over 5 years.
In addition, the README says

  Originally, we thought we might more deeply integrate the two projects
  (possibly even going as far as a rebranding!). However, over time it
  became clear that that wasn't really necessary to fulfil our goal of
  making them work well together. Ultimately, we decided to focus on
  adding features to both projects rather than doing work just to
  combine them.

So we don't need to run CI jobs related to the canal at this situation.

* network_plugin/custom_cni: add CNI to apply provided manifests

Add a new simple custom_cni to install provided Kubernetes manifests.
This could be useful to use manifests directly provided by a CNI when
there are not support by Kubespray (i.e.: helm chart or any other manifests
generation method).

To verify the hardening method works always.
The configuration comes from docs/hardening.md

Fix yaml format of hardening.yml

Add condition to skip 040 test for hardening

To test Kubespray on Rocky Linux 8 with vagrant, this adds it to
the Vagrantfile.

* [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

* 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
