    PY3: Ensure _refresh is passed str type for reason

    Drop the use of oslo.i18n's Message class when defining the reason
    argument that is passed to _refresh(). Ensuing code that _refresh()
    uses, in particular pymysql [1], expects a unicode str type rather
    than an oslo_i18n._message.Message type.
