instack-undercloud is no longer in use by the TripleO project. Removing
the code to avoid confusion. Stable branches will continue to be
maintained for their life however no new features should be added.

Blueprint: remove-instack-undercloud
In order to improve the user experiance, we should validate that the
provided local_interface actually exists prior to trying to configure
the undercloud with it. If net_config_override is not used and the
local_interface does not exist, an error will be returned to the
user early on in the installation process. Additionally if the user
does not have an undercloud.conf, a warning is printed to show that
the defaults will be used.
