Bug report

Work was done last year to ensure that when /tmp and /var/tmp are hardend with noexec, cloud-init will use an alternative path under /usr/lib/cloud-init

However, /usr/lib/cloud-init/clouddir is created as world writable and left behind after cloud-init has exited.

Steps to reproduce the problem

Run cloud-init with a /tmp and /var/tmp that are mounted with noexec

If possible, /usr/lib/cloud-init/clouddir should be created as non-world read/writable. But if that's not possible, at the least it should be removed when cloud-init exits.
