To save on network resources, it is required to prestage the
ostree_repo and the container images. When installation of a
subcloud is done, it is preferred that the prestaged ostree
repo and the prestaged container images are used, instead of
downloading them.
The prestaged container images are copied over to
/opt/platform-backup from the mounted media containing the
prestage iso.
Test Plan:
PASS: Verify that the prestaged container images are copied to
/opt/platform-backup/<release version>.
PASS: Verify that the ostree_repo is not pulled from the system
controller but from /opt/platform-backup for installation.
