For some reason buildah is failing on images which already have a
WORKDIR set (such as the tempest image). This change sets the WORKDIR
to / to avoid this failure.

This patch adds a new rpm_install tasks which can be used
to build a new container layer from a set of local RPMs.
This is useful for building contains locally with no network
connectivity.
As part of the change the existing Yum update Dockerfile.j2 was
renamed to Dockerfile-yum.j2 to make it more specific.
