Ansible playbook to perform automated selfchecks
    
    To run selfcheck test on a clean system where
    libabigail is not installed, we will have to perform
    few tasks like installing libabigail's build
    dependencies, compiling libabigail after cloning
    source code, cloning libabigail-selfcheck repo and
    then running selfcheck.py. All these tasks has
    been automated in ansible playbook setup.yaml.
