    Support Optional Super User in Instance Create

    The creation of initial users and/or databases is supported in an
    instance-create request, but the creation of a super/root user is
    not. Granted, it's possible to create or reset the root user, but it
    must be done as a separate request, after the instance has completely
    initialized.

    Changeset: If CONF.root_on_create == True, a UUID is generated for
    the root user's password and is returned in the instance-create
    response as the "password" property/field.
