[shellymiron]

This PR present the e2e/molecule tests written by QEs (@smiron @epassaro) to manage e2e flows using the validated content roles. in the future those will run in a proper CI.

Molecule is an ansible-testing framework, that allows to write playbooks to validate/assert expected results of a role output.
The structure of the folder will be as follow:

• each role has a testing folder, those testing folders called "Molecule scenario"
• each testing folder will contain: vars, tasks, post_validations and scenario (if needed) folders.
• post_validations tests can be written as an ansible playbook or as a pytest file (currently written as a playbook).
• each testing folder/Molecule scenario will run twice (molecule use idempotence mechanism)
• makefile is created to run the molecule test per scenario including all the necessary dependencies
