* add parametrization to molecule_run.sh

* [CI] split molecule tests to allow parallelization of work

* [terraform] use modern day equinix metal provider

* [CI] ensure packet job tests metal

* [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

This fixes the following types of failures:
- empty-string-compare
- literal-compare
- risky-file-permissions
- risky-shell-pipe
- var-spacing

In addition, this changes .gitlab-ci/lint.yml to block the same issue
by using the same method at Kubespray CI.

* 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

* OEL7: Fix CentOS7 Extras for OEL7

* Molecule: add logs collection for jobs

* 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

tf-elax_ubuntu18-calico is so flake today. The test job is failed
due to SSH connectivity check error after deploying virtual machines
which are used for Kubernetes nodes.
This allows failure on the job to see the test situation without
pull request merger failures.

* Ansible: move to Ansible 3.4.0 which uses ansible-base 2.10.10

* Docs: add a note about ansible upgrade post 2.9.x

* CI: ensure ansible is removed before ansible 3.x is installed to avoid pip failures

* Ansible: use newer ansible-lint

* Fix ansible-lint 5.0.11 found issues

* syntax issues
* risky-file-permissions
* var-naming
* role-name
* molecule tests

* Mitogen: use 0.3.0rc1 which adds support for ansible 2.10+

* Pin ansible-base to 2.10.11 to get package fix on RHEL8

* Calico: add Wireguard support

* CI: Add Calico Wireguard scenario
