Bug Description

After upgrade from Ussuri to Yoga, ceilometer doesn't work properly. Metric measures are generated for old servers. But for new created servers, metric measures are unable to be published to gnocchi.

The issue happens in batch_measures function:

    def batch_measures(self, measures, resource_infos):
        # NOTE(sileht): We don't care about error here, we want
        # resources metadata always been updated
        try:
            self._gnocchi.metric.batch_resources_metrics_measures(
                measures, create_metrics=True)
        except gnocchi_exc.BadRequest as e:
            if not isinstance(e.message, dict):
                LOG.debug("Tristan: if not isinstance ")
                raise
            if e.message.get('cause') != 'Unknown resources':
                LOG.debug("Tristan: if cause != Unknown resources ")
                raise

Here we test if e.message is a dict. In my case ceilometer gets a message with a dict. But for some reason the character "'" in the exception message from gnocchi-api is converted to "'", that breaks this part of code.
