If ifcfg-eth0 is defined but does not exist, this can cause the nodes to
fail to get an IP address on initial provisioning. This patch removes it
when the image is built to ensure we don't end up with a bad interface

It seems as though w/ CentOS-8.3 ens3 has crept
back into play. Ensure it's not in the overcloud
images. See bug for details.
(cherry picked from commit d072a79acf)
There is a bug in the CentOS 8 image where the ens3 interface file
exists. We should clean that up if it exists to prevent issues when
booting. We manage the interfaces later with os-net-config so we don't
want them to exist in the image.
