Due many patterns of Linux distributions, it is difficult to install
ansible dependencies as system-wide stably.
Apart of Kubespray doc[1] recommends to use venv to avoid such issue,
and this applies venv usage to the other parts of the doc.

terrform/openstack: Fix templating of ansible_ssh_common_args in no_floating.yml if used as TF module (#8646)

* terraform/openstack: Use path.module for ansible_bastion_template.txt

This extends on #7643 by not using path.root, but switching to path.module
to allow use of the terraform code as a module itself. This change then keeps
all calls to the template file stable even for that use-case.

* terraform/openstack: Make sed calls fail on errors

By using a single call with two replacements to use of sed will create proper exit codes
and allowing for errors to be recognized by terraform.

This adds a unit test for the function.

Also, do not create unneeded resources (target pools are charged and should
only be created when needed).

When trying to run print_hostnames of inventory.py, it outputs the following
error:

 $ CONFIG_FILE=./test-hosts.yaml python3 ./inventory.py print_hostnames
 Traceback (most recent call last):
   File "./inventory.py", line 472, in <module>
     sys.exit(main())
   File "./inventory.py", line 467, in main
     KubesprayInventory(argv, CONFIG_FILE)
   File "./inventory.py", line 92, in __init__
     self.parse_command(changed_hosts[0], changed_hosts[1:])
   File "./inventory.py", line 415, in parse_command
     self.print_hostnames()
   File "./inventory.py", line 455, in print_hostnames
     print(' '.join(self.yaml_config['all']['hosts'].keys()))
 KeyError: 'all'

because it is missed to load a hosts config file before printing hostnames.
This fixes the issue.

Use jinja2 template and ansible to expand variables.

Fixed the problem when call ansible-playbook contrib/mitogen/mitogen.yml
"The error was: 'dict object' has no attribute 'section'"

Special notes for your reviewer:

Does this PR introduce a user-facing change?:

Use openstack_networking_port_v2 and openstack_networking_floatingip_associate_v2
to attach floating ips. This gives us more flexibility on disabling port security
when binding instances directly on provider networks in private cloud scenario.

* terraform/gcp: Do not create unused subnetworks

By default terraform creates a subnetwork in each 39 regions

* terraform/gcp: Upgrade to latest google provider

... where "one of source_tags, source_ranges, or source_service_accounts must be defined"

* Use sysctl_file_path variable for all sysctl_file locations

* Add sysctl_file_path variable to kubespay-defaults

* Remove previously used sysctl file locations if present

* Use explicit filename in roles/kubernetes/node/defaults/main.yml

* Defaults: use explicit value

* fixes issues in vSphere Terraform contrib. #8436

* fix formatting

* add variables to the main module and document changes

* add missing newline

* Fix terraform Warning

Version constraints inside provider configuration blocks are deprecated

Terraform 0.13 and earlier allowed provider version constraints inside the
provider configuration block, but that is now deprecated and will be removed
in a future version of Terraform. To silence this warning, move the provider
version constraint into the required_providers block.

* Fix terraform Warning: Quoted references are deprecated

* terraform: Update GCP Ubuntu to latest LTS

* contrib: add cloud-init support for terraform vms

This change enables instance customization via cloud-init,
for example: additional CA certs, custom SSH access etc.

* contrib: update docs for terraform cloud-init

* contrib: disable yamllint in cloud-init

require-starting-space rule breaks cloud-init header

* contrib: documenation formatting

* yamllint: disable comments related checks

* docs: markdown formatting

When running ansible-lint directly, we can see a lot of warning
message like

  risky-file-permissions File permissions unset or incorrect

This fixes the warning messages.

All container image versions were defined in download/defaults/main.yml
except containerd.
The inconsistency caused the offline script(generate_list.sh) could not
output the URL of containerd image.
This moves the definition into a valid file.
In addition, this adds host_os to generate_list.sh for downloading
krew from a valid URL.

* use pre-existing floating IP for bastion

* document bastion_fips in readme
