I am tweaking an image based on SLE-12-JeOS kiwi template.

If I make a mistake in repository configuration or package selection that would
ordinarily cause zypper to complain, kiwi aborts the build with message:

Problem occured during or after installation or removal of packages:
Installation aborted by user

That isn't quite helpful as it does not tell me the troubled package choice, or
the reason why zypper cannot install the package.

Please provide zypper output to help with debugging in such cases.
