Allow specify tenant:user in user.

We allow having the syntax tenant:user in user since this would make
things easier when switching from auth 1.0 to auth 2.0 and not having to
specify a tenant_name.

In the feature we should use the auth functions from keystoneclient and
be done with those changes, we could then auth by user/tenant-ID.
