* 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
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.

* contrib/terraform/exoscale: Rework SSH public keys
Exoscale has a few limitations with `exoscale_ssh_keypair` resources.
Creating several clusters with these scripts may lead to an error like:
```
Error: API error ParamError 431 (InvalidParameterValueException 4350): The key pair "lj-sc-ssh-key" already has this fingerprint
```
This patch reworks handling of SSH public keys. Specifically, we rely on
the more cloud-agnostic way of configuring SSH public keys via
`cloud-init`.
* contrib/terraform/exoscale: terraform fmt
* contrib/terraform/exoscale: Add terraform validate
* contrib/terraform/exoscale: Inline public SSH keys
The Terraform scripts need to install some SSH key, so that Kubespray
(i.e., the "Ansible part") can take over. Initially, we pointed the
Terraform scripts to `~/.ssh/id_rsa.pub`. This proved to be suboptimal:
Operators sharing responbility for a cluster risk unnecessarily replacing resources.
Therefore, it has been determined that it's best to inline the public
SSH keys. The chosen variable `ssh_public_keys` provides some uniformity
with `contrib/azurerm`.
* Fix Terraform Exoscale test
* Fix Terraform 0.14 test
* [terraform/aws] Fix Terraform >=0.13 warnings
Terraform >=0.13 gives the following warning:
```
Warning: Interpolation-only expressions are deprecated
```
The fix was tested as follows:
```
rm -rf .terraform && terraform0.12.26 init && terraform0.12.26 validate
rm -rf .terraform && terraform0.13.5 init && terraform0.13.5 validate
rm -rf .terraform && terraform0.14.3 init && terraform0.14.3 validate
```
which gave no errors nor warnings.
* [terraform/openstack] Fixes for Terraform >=0.13
Terraform >=0.13 gives the following error:
```
Error: Failed to install providers
Could not find required providers, but found possible alternatives:
hashicorp/openstack -> terraform-provider-openstack/openstack
```
This patch fixes these errors.
This fix was tested as follows:
```
rm -rf .terraform && terraform0.12.26 init && terraform0.12.26 validate
rm -rf .terraform && terraform0.13.5 init && terraform0.13.5 validate
rm -rf .terraform && terraform0.14.3 init && terraform0.14.3 validate
```
which gave no errors nor warnings for Terraform 0.13.5 and Terraform
0.14.3. Unfortunately, 0.12.x gives a harmless warning, but
with 0.14.3 out the door, I guess we need to move on.
* [terraform/packet] Fixes for Terraform >=0.13
This fix was tested as follows:
```
export PACKET_AUTH_TOKEN=blah-blah
rm -rf .terraform && terraform0.12.26 init && terraform0.12.26 validate
rm -rf .terraform && terraform0.13.5 init && terraform0.13.5 validate
rm -rf .terraform && terraform0.14.3 init && terraform0.14.3 validate
```
Errors are gone, but warnings still remain. It is impossible to please
all three versions of Terraform.
* Add tests for Terraform >=0.13
Now markdownlint covers ./README.md and md files under ./docs only.
However we have a lot of md files under different directories also.
This enables markdownlint for other md files also.
If a branch name contains '.sh', current shellcheck checks the branch
file under .git/ and outputs error because the format is not shell
script one.
This makes shellcheck exclude files under .git/ to avoid this issue.
* 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)
