Revert "Allowing ubuntu element use local image"

Browse source 
This reverts commit 1f4fb1d7a5.

This unfortunately wasn't actually tested.  Because the image-based
tests run sequentially, a prior failure in the centos-8 job meant the
ubuntu job never ran.

This is failing with

 10-cache-ubuntu-tarball: line 28: DIB_LOCAL_IMAGE: unbound variable

There is also a seemingly unused variable DIB_IMAGE_LOCAL_FILE; I'm
not sure what this is doing.

For now revert, and it can be re-proposed with appropriate testing.

settings to allow insecure/unuthenticated repositories.
* Setting ``DIB_OFFLINE`` will prevent to download again the source image
if is already present in to $DIB_IMAGE_CACHE path.
* Setting ``DIB_LOCAL_IMAGE`` in combination with ``DIB_OFFLINE`` to
use a image from a local source (full path and file name) and not
download image from internet. Local source for release Trusty and Xenial
have to be tar.gz format. For other more recent release get the squashfs image.
