inconsistent i18n message

[Kun Huang]

in cinder/exception.py: https://github.com/openstack/cinder/blob/master/cinder/exception.py#L242

message = _("Invalid metadata") + ": %(reason)s"

is not consistent i18n usage. In most of cases, we use _() for whole string instead of leaving something out.

More than inconsistent, some text in leaving strings may be not translated, for example, ':' in English is different '：' in Chinese.

    fix inconsistent i18n log message

    An inconsistent example:
        imessage = _("Invalid metadata") + ": %(reason)s"
    This is not consistent i18n usage. In most of cases, we use _() for
    whole string instead of leaving something out.

    More than inconsistent, some text in leaving strings may be not
    translated, for example, ':' in English is different '：' in Chinese.
