Save needed stack outputs in working_dir

With ephemeral-heat, we need to save the needed stack outputs in the
working_dir so that the values can be used when needed if the stack is
no longer around.

With the outputs saved, the stack object no longer needs to be passed to
workflows.deployment.config_download and
workflows.deployment.get_hosts_and_enable_ssh_admin, only the stack name
and output values are needed.
