[PATCH 1/2] ansible_cfg: add python interpreter support

[Daniel Gomez <da.gomez@kernel.org>]

From: Daniel Gomez <da.gomez@samsung.com>

Ansible Python interpreter can be set globally in [defaults] section
of ansible.fg with the interpreter_python key. Add support for it in
Kconfig ansible_cfg and allow cli to overwrite the the value.
