[Ovirt-devel] [PATCH Repost] Remove ovirt-node-image-pxe package

[Perry Myers]

This patch series removes ovirt-node-image-pxe and instead relies on the user
running ovirt-pxe after install of ovirt-node-image RPM.  Appliance recipe
is tweaked to do this as well.

This is a repost of the original patch series and corrects a problem identified
by Alan where after the tmp dir is deleted on the appliance cobbler sync would
fail.
