    make enforce_type=True in CONF.set_override

    Method CONF.set_override to change config option's
    value with designated value in unit test, but never check if the
    designated vaule is valid. Each config option has a type like StrOpt,
    BoolOpt, etc. StrOpt with parameter choices only allows values in set
    of choices. In short, each config option has limitation for type
    and value. In production code, oslo.conf can ensure user's input is
    valid, but in unit test, test methods can pass if we use method
    CONF.set_override without parameter enforce_type=True even we pass wrong
    type or wrong value to config option. This commit makes sure calling
    method CONF.set_override with enforce_type=True and fixes violations.

    Note: We can't set enforce_type=True by default in oslo.config now, it
    may break all project's unit test. We can switch enforce_type=True by
    default when all project fix violations like this commit.
