Comment 8 for bug 1652002

The reason is that sometimes cloudinit fails completely on a node. It happens the following way:
1. Cloudinit creates a folder in tmp (using mkdtemp)
2. Cloudinit mounts config drive image into it
3. Cloudinit reads the configuration
4. Cloudinit unmounts the folder
5. Cloud init fails to delete the folder because there is no such folder anymore !!!
