Create symlinks for failed builds logs

This allows to know which image failed to build without having to parse
the huge job-output.txt file.

This commit creates a convenient 000_FAILED_image_name.log symlink to
the relevant log files when kolla is configured to output to a log
directory. This creates symlinks only for the parent image with error,
i.e. it skips images that failed to build because of parent error.
