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

* updated ansible pinning to prevent more possibilities of breaking changes

* more exact pinning of ansible version

* more exact pinning of ansible version and also all the rest

* added testing requirements.txt pinning settings

* removed boto from testing requirements.txt

- Creates and defaults an ansible variable for every configuration option in the `kubeproxy.config.k8s.io/v1alpha1` type spec
  - Fixes vars that were orphaned by removing non-kubeadm
  - Fixes previously harcoded kubeadm values
- Introduces a `main` directory for role default files per component (requires ansible 2.6.0+)
  - Split out just `kube-proxy.yml` in this first effort
- Removes the kube-proxy server field patch task

We should continue to pull out other components from `main.yml` into their own defaults files as I did here for `defaults/main/kube-proxy.yml`. I hope for and will need others to join me in this refactoring across the project until each component config template has a matching role defaults file, with shared defaults in `kubespray-defaults` or `downloads`

* Remove Vault

* Remove reference to 'kargo' in the doc

* change check order

Only exclude buggy Ansible v2.7.0 (https://github.com/ansible/ansible/issues/46600#issuecomment-433863628)

Fixup #3589

* Fix bootstrap_os/ubuntu idempotency

* Update bastion role

* move container_engine in sub-roles

* requires ansible 2.5

* ubuntu18 as first CI job

* Move front-proxy-client certs back to kube mount

We want the same CA for all k8s certs

* Refactor vault to use a third party module

The module adds idempotency and reduces some of the repetitive
logic in the vault role

Requires ansible-modules-hashivault on ansible node and hvac
on the vault hosts themselves

Add upgrade test scenario
Remove bootstrap-os tags from tasks

* fix upgrade issues

* improve unseal logic

* specify ca and fix etcd check

* Fix initialization check

bump machine size

Use image family for picking latest coreos image
Update python deps

Also update to ansible 2.3.2

Required for an RPM package builds with the contrib/ansible-kubespray.spec

ansible 2.2.2.0 has an [issue]() that causes problems for kargo:

```
(env) kargo ᐅ env/bin/ansible-playbook upgrade-cluster.yml 
ERROR! Unexpected Exception: 'Host' object has no attribute 'remove_group'
```

Pinning ansible to 2.2.1.0 resolved this for me.

Ansible 2.2.1 requires jinja2<2.9, see <https://github.com/ansible/ansible/blob/v2.2.1.0-1/setup.py#L25>,
but without explicit limiting upper jinja2 version here pip ignores
Ansible requirements and installs latest available jinja2
(pip is not very smart here), which is incompatible with with
Ansible 2.2.1.
With incompatible jinja2 version "ansible-vault create" (and probably other parts)
fails with:
  ERROR! Unexpected Exception: The 'jinja2<2.9' distribution was not found 
  and is required by ansible
This upper limit should be removed in 2.2.2 release, see:
<https://github.com/ansible/ansible/commit/978311bf3f91dae5806ab72b665b0937adce38ad>

Jinja 2.* releases are published under `Jinja2` name.

Added Jinja 2.8 Requirements to docs and pip requirements file which
is needed to run the current Ansible Playbooks.

This allows you to simply run `vagrant up` to get a 3 node HA cluster.

* Creates a dynamic inventory and uses the inventory/group_vars/all.yml
* commented lines in inventory.example so that ansible doesn't try to use it.
* added requirements.txt to give easy way to install ansible/ipaddr
* added gitignore files to stop attempts to save unwated files
* changed `Check if kube-system exists` to `failed_when: false` instead of
`ignore_errors`
