QueryMultiSeriesAsync should return "partial" if responses are truncated by InfluxDB

[tbraun-hk]

InfluxDB offers the possibility to restrict the amount of rows returned by a (multi-)query. In order to do so, you need to set the configuration variable max-row-limit to a value > 0.

If a result is truncated because of this, InfluxDB indicates it by returning partial: true in the response. See https://docs.influxdata.com/influxdb/v1.7/administration/config/ , section "max-row-limit" for details.

I'd be happy to provide a pull request to your library that includes this information in QueryMultiSeriesAsync , but I'm not really sure how this information would fit best into the current response model. Would it be OK to include an additional field bool? partial in IInfluxSeries and to optionally set this field in every instance of IInfluxSeries if InfluxDB truncated a response?
