Comment 3 for bug 1538645

After discussion with Alexander Gordeev it looks like we could not solve it fast, because fuel-agent at now moment do not support interruption. In other case we can run several fuel-agent without any problem. So looks like solution change image and yaml destination for some uniq for every generation (for example, include task id to path). It will safe us from problem with running several fuel-agent for one cluster.

Also we could not guarantee stable work for cluster after stop deployment in 8.0 or early version, so this bug should be high, because it can easily solved by using 'reset' and deploy after.
