    Support users without projects in keystone library

    Update the ensure_user and ensure_user_role commands and dependent
    functions to allow creation of and role assignment to a user without
    specifying a project.

    This will allow use of the keystone library for creating users, such as
    the heat stack admin, within only a domain.
