Code Issues Proposed changes

Added download-debian-installer script 

We are going to download debian-installer initrd and kernel
from one of user defined ubuntu repos. We implemented this
as a pre-provision task which is supposed to run a shell
script.

This patch introduces this script for downloading
debian-installer initrd image.
