Password is not written back to openstack metadata service when an instance is rebuilt #183
Description
When an Openstack instance is rebuilt (openstack server rebuild ...), the new password for Admin genereated by cloudbase-init is set in Windows, but it is not written back to openstack's metadata service since it is already set. The old password is of course still there, since the VM was rebuilt with the rebuild API from Openstack Nova.

The results is of course that you're not able to login to the Windows instance after doing a rebuild.
