Trustee sections should support auth_type option

Hi Matt, so this appears to be a follow-on from our previous work ref https://review.openstack.org/#/c/254145/4/heat/common/context.py right?

I'm not quite clear what there is to do here, because we pass the entire trustee section into auth.load_from_conf_options, we don't explicitly do anything related to auth_type, can you provide any pointers to what other projects are doing in this regard?

The only thing I did was hard-code our requirement for the v3password plugin via the list_opts, beause as far as I'm aware no other plugin will currently work in the context of our trustee auth requirements (we have to be able to do non-expiring, e.g password based auth, and it must support delegation via trusts)

If you can provide a bit more detail here I'll be happy to take a look, thanks!

I think it just simply denotes the fact that "auth_plugin" option name is deprecated, the new one is "auth_type"
