Add associate_public_ip_address flag #65
Description
Packer CloudStack plug-in always try to associate a public IP address. Some CloudStack instances do not allow users to associate public IP address to virtual machines, leading Packer to fail with message "Failed to associate public IP address...".
Amazon EBS plugin for instance has a flag associate_public_ip_address allowing sources not to be associated to public IP address. Can we have this flag for CloudStack too?
