[RFC PATCH 2/2] ansible.cfg: generate an ansible.cfg file in TOPDIR

[Chuck Lever <cel@kernel.org>]

From: Chuck Lever <chuck.lever@oracle.com>

I need an ansible.cfg that is generated by the Kconfig menu, but
whose pathname is selected dynamically based on where kdevops is
being run rather than having that path baked into the .config.
