Add support to create a Keystone domain for Heat

Heat in Kilo will require configuration that specifies a domain
that is set up in Keystone in its configuration. To facilitate that
undeprecate initialize_for_heat(), wean it off its use of the admin
token, and add a CLI utility to make calling it from -incubator easy.
