log_handler miss some log information

[Tiantian Gao]

log_handler:PublishErrorsHandler just emit the `msg` attribute of record. But many times we log with extra arguments, like "LOG.debug('start %s', blabla)", which will result in only show "start %s" in notification payload.

    When using PublishErrorsHandler, it will missing user-supplied arguments.
    For example, do LOG.info("blabla %s", "foo"), the payload only contains
