Operational experience shows that the current Infix Fail Secure mode,
introduced in ca9daef, does not work in practice.
The factory datastore in sysrepo is created at boot with the YANG models
and the factory-config file. When the factory-config file is generated
from older versions of these models, the resulting datastore may fail to
pass the validation and system will end up in an unrecoverable state.
Instead, both the factory-config and failure-config must be created at
every boot to match the YANG models in the active Linux image. This
ensures loading the YANG models will always work and the system can
proceed to attempt to load startup-config to the running datastore.
If loading startup-config fails we can fall back to failure-config,
which like factory-config, will then provide a way to log in an dianose
the system.

This allows you to define a single "logical" config that can be
tailored to the specific system based on the available interfaces,
base MAC address etc.
When researching the systemd tmpfiles.d implementation I discovered the
effort to standarize on /usr/share/factory as a generic factory defaults
for Linux systems. This patch adds a small example factory.cfg file
that is installed as /usr/share/factory/cfg/startup-config.cfg. The
tmpfiles.d backend will then install it as /cfg/startup-config.cfg if
that file is missing at boot. Confd does the rest to bootstrap our
(by default) empty sysrepo db with this startup-config.
