Ansible is distributed under GPL-3.0 license and certain restrictions
are applied when its code is imported as Python library. The only safe
way to call GPL code is via general interface, e.g. CLI.
This patch removes all direct linking of Ansible code and executes
all actions via command line. It is now user responsibility to install
Ansible executable on the system.
