To not install these on the images, create a new scripts directory to
hold them.
Create new copy-release-tools-scripts role to copy the files over,
we do not need using legacy-copy-project-config-scripts anymore since
everything is copied elsewhere.
Add the role to all playbooks that use release-tools scripts.
