Comment 8 for bug 1620301

From test on the #299 snapshot [1]:
Updating : fuel-bootstrap-cli-9.0.0-1.mos291.noarch 26/74
warning: /etc/fuel-bootstrap-cli/fuel_bootstrap_cli.yaml saved as /etc/fuel-bootstrap-cli/fuel_bootstrap_cli.yaml.rpmsave

This means our script makes change on configuration -> everything works fine now
