Kai Lueke 1319e4c95a ci-automation: Move image change report to own file
To review the image changes and the changelog more easily and in case
of fixes, iterate over it without rebuilding the image, move this logic
to its own file where a new job could call it.

# image_changes() should be called w/ the positional INPUT parameters below.
# OS image differences display stub.
# This script will display the differences between the last released image and the currently built one.
#
# PREREQUISITES:
#
# 1. Artifacts describing the built image (kernel config, contents, packages, etc.) must be present in build cache server.
# 2. Scripts repo version tag of OS image version to be built is available and checked out.
#
# INPUT:
#
# 1. Architecture (ARCH) of the TARGET OS image ("arm64", "amd64").
#
# OPTIONAL INPUT:
#
# (none)
#
# OUTPUT:
#
# 1. Currently the script prints the image differences compared to the last release and the changelog for the release notes but doesn't store it yet in the buildcache.

# Run a subshell, so the traps, environment changes and global
