* Add new AnsibleK8SModule class
This class is intended to replace part of the K8SAnsibleMixin class and
is part of a larger refactoring effort.
* Fix sanity errors
* Fix unit tests
* Add mock to test requirements
Add support for:
- K8S_AUTH_HOST
- K8S_AUTH_API_KEY
- K8S_AUTH_VERIFY_SSL
- K8S_AUTH_SSL_CA_CERT
This commit also refactor the way we pass K8S related configuration to `helm`:
All the calls are now done in a new module_utils module (`helm.py`).
The handling of the `kube_*` variables has also been moved in this new
module.
We need https://github.com/helm/helm/pull/8622 to be able to ignore the
certificate validation. As a workaround, the generate a temporary
kubeconfig configuration file.
Closes: #279
