WIP establish regular molecule tests

[fatz]

What problem does this PR solve?:
Currently only basic testing is done against a full image build. But changes in ansible are not covered by tests. This actually lead to customer facing issue.

Molecule was in a quite unmaintained state. To improve code quality its important to establish a test driven approach making changes to the ansible code in KIB.

This PR will establish automated molecule testing for all supported OSes by using AWS instances for testing.

We'll not cover provider specific code but focus on the supported Distributions

Action items:

• make sure ansible ( without the sysprep step ) is idempotent so while developing new features ansible could be run over and over again
• ensure molecule works from within the devkit container
• establish private AWS GH runner for this repository
• add github actions to run the molecule suite whenever there are changes in /ansible
• add github action to run special GPU related tests whenever the /ansible/roles/gpu has changes

Which issue(s) does this PR fix?:

no jira

Special notes for your reviewer:
This is branched off my latest changes about cloud-init due to those changes adding a molecule test.

Does this PR introduce a user-facing change?:

Hey @supershal @faiq I've took another look into this PR and rebased it.

It adds regular molecule test to improve ansible code quality as molecule does not only testing the run results but also doing linting of ansible.
