tests/requirements.txt links to tests/requirements-2.12.txt, so
Kubespray uses ansible 2.12 by default for testing. However we
forgot to update testcases_prepare.sh to use ansible 2.12.
This updates testcases_prepare to use ansible 2.12.

* add parametrization to molecule_run.sh

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

* 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

* 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

Fix-CI: python was upgraded in CI to 3.10 and pathlib is now included in python base making this dependency break the CI (#8153)

Although these errors are not important, they affect the code specification.

* 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

* Fix ansible detection for python3 and ubuntu

* Fix oracle missing centos-extras repo for containerd/docker dependencies

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.

* containerd docker hub registry mirror support

* add docs

* fix typo

* fix yamllint

* fix indent in sample
and ansible-playbook param in testcases_run

* fix md

* mv common vars to tests/common/_docker_hub_registry_mirror.yml

* checkout vars to upgrade tests

* add strategy mitogen_linear when installed mitogen

* add small docs

Rename playbook file

The raw action executes as a regular Mitogen connection, which requires Python on the target, so add strategy: linear to bootstrap-os role playbook.

* add mitogen to  CI test
fix typo

* enable mitogen test on deploy-part1 tests
change version from master to release
download tar.gz archive

* run all CI tests with mitogen

* disable mitogen with upgrade CI tests

* enable mitogen on CI tests via env vars

* disable mitogen on CI test by default, enable on some different OS

* disable mitogen CI test on centos8
(get error  /usr/bin/python: No such file or directory)

* Add CI_TEST_VARS to tests

* Update flannel to 0.12.0 (with new manifests) and disable tx/rx
offloading in networking test

* requirements.txt: Bump versions

Ansible 2.8+ allow ansible_python_interpreter autodetection

Signed-off-by: Etienne Champetier <champetier.etienne@gmail.com>

* tests: do not force ansible_python_interpreter

we do not expect people to set ansible_python_interpreter, so we should not set it in the CI
