This fixes markdown failures on contrib/terraform.

* Added gcp terraform support

* Added http/https firewall rule

* Ignoring lifecycle changes for attached disks on the google_compute_instance

* [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

This fixes markdownlint failures under contrib/network-storage and
contrib/vault.

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.

Added "boto3" as dependency in "requirements.txt" which is required by "kubespray-aws-inventory.py".

* add custom sec groups

* make sure groups are applied only when created

* fix spacing

* Add note about changing private IP in admin.conf.

When I run kubespray, a load balancer is created which should be used instead of the ip of the controller node.

* Procedure to find load balancer and update admin.conf

When I run kubespray, a load balancer is used instead of the private ip of the controller.

k8s_master_no_etcd_fips should not be input var

I kept seeing `TLS handshake error from 10.250.250.158:63770: EOF` from two IP addresses that correlate to my ELB. Changing the health check from TCP to HTTPS stopped the errors from being generated.

It was documented as if it were an Ansible variable, but it is a Terraform variable.
This also means the colon syntax was incorrect. TF variables are assigned with an equals sign.

The official word is OpenStack, not Openstack as [1].
This replaces it with OpenStack in the docs.

This changes MetalLB contrib to one of addons for deploying MetalLB with
Kubernetes cluster deployment. By the default, Kubespray doesn't deploy
MetalLB addon.

inventory_builder creates hosts.yaml file with hostnames like "node1",
"node2", etc. Even if specifying override_system_hostname=false, the
output of "kubectl get nodes" shows those hostnames ("node1", etc.)
without using actual hostnames.
To solve this issue, this adds an option USE_REAL_HOSTNAME to get
actual hostnames when creating hosts.yaml file instead of "node1", etc.

Since MetalLB v0.8[1], metallb:speaker has started publishing an event
nodeAssigned on k8s resource.
To support MetalLB v0.8+, this allows metallb:speaker to create events.

[1]: https://github.com/metallb/metallb/commit/5cc6e237766d742fccde1a8a325baba2608024df#diff-60053ad6fecb5a3cfabb6f3d9e720899R246

If running MetalLB v0.7.3 on k8s v1.18.2, metallb pods output the
following parsing error of v1.ServiceList:

  $ kubectl logs controller-dbb46cf84-fw8h8 -n metallb-system
  {
    "caller":"reflector.go:205",
    "level":"error",
    "msg":"go.universe.tf/metallb/internal/k8s/k8s.go:231:
      Failed to list *v1.Service: v1.ServiceList:
        Items: []v1.Service: v1.Service: ObjectMeta:
        v1.ObjectMeta: readObjectFieldAsBytes:
        expect : after object field, parsing 1605

Then an external IP address is never allocated to the Service of
LoadBalancer type.
By updating MetalLB version to the latest v0.9[1] today, this issue
can be solved.

This updates MetalLB README as following
- Remove unnecessary markdown to read it easily on github
- Make words consistency (kubernetes, loadbalancer)
- Add change-required option

Due to lack of requirements installation on Azure README, the error
can happen:

 "The ipaddr filter requires python's netaddr be installed on the
  ansible controller"

It is nice to add the installation for Azure users.

apply-rg.sh was for Azure command version 1("azure" command) and the
command is old and version 2("az" command) is officially used today.
apply-rg_2.sh was for the version 2. In addition, the README[1] says
we need to run apply-rg.sh for applying templates.

This renames apply-rg_2.sh to apply-rg.sh for common usages of the
version 2.

[1]: https://github.com/kubernetes-sigs/kubespray/tree/master/contrib/azurerm#generating-and-applying

The ansible-playbook needs to ssh-login to Azure virtual machines with
ssh keypair, and users need to specify ssh_public_keys for their own
ssh public key. The change of ssh_public_keys is mandatory.
So this updates contrib/azurerm/README.md to explain that.
In addition, the path of all.yml was wrong. That also is updated with
this.

apply-rg_2.sh uses 'az group deployment' command but the command is
deprecated like the following warning message:

"This command is implicitly deprecated because command group
 'group deployment' is deprecated and will be removed in a future release.
 Use 'deployment group' instead."

This updates these deprecated commands.

FYI: The command has been deprecated since [1] on azure-cli side.
