using stack_user_domain_name in heat.conf will fail stack creation.

[Ethan Lynn]

When set stack_user_domain_name instead of stack_user_domain_id in heat.conf
heat stack-create will fail with below error message.

It fails at here:
https://github.com/openstack/heat/blob/master/heat/common/heat_keystoneclient.py#L490-L493
        domain_project = self.domain_admin_client.projects.create(
            name=project_name,
            domain=self.stack_domain,
            description=desc)

self.stack_domain is domain name, not domain id.
It seems keystone can't accept domain name in porjects.create()

I think we should get domain_id from domain name before create domain project or user.

Fix proposed to branch: master
Review: https://review.openstack.org/132955

[Ethan Lynn (ethanlynn)]

As chef deployer cookbook in community only sets stack_user_domain_name in heat.conf, heat will not work after deploy.

This patch is badly needed.
