Roman Khavronenko 0d4f4b8f7d (app\|lib)/vmstorage: do not increment `vm_rows_ignored_total` on NaNs (#7166 ) `vm_rows_ignored_total` metric is a metric for users to signalize about ingestion issues, such as bad timestamp or parsing error. In commit `a5424e95b3` this metric started to increment each time vmstorage gets NaN. But NaN is a valid value for Prometheus data model and for Prometheus metrics exposition format. Exporters from Prometheus ecosystem could expose NaNs as values for metrics and these values will be delivered to vmstorage and increment the metric. Since there is nothing user can do with this, in opposite to parsing errors or bad timestamps, there is not much sense in incrementing this metric. So this commit rolls-back `reason="nan_value"` increments. ### Describe Your Changes Please provide a brief description of the changes you made.

(app|lib)/vmstorage: do not increment vm_rows_ignored_total on NaNs (#7166 )

`vm_rows_ignored_total` metric is a metric for users to signalize about
ingestion issues, such as bad timestamp or parsing error.
In commit
a5424e95b3
this metric started to increment each time vmstorage gets NaN. But NaN
is a valid value for Prometheus data model and for Prometheus metrics
exposition format. Exporters from Prometheus ecosystem could expose NaNs
as values for metrics and these values will be delivered to vmstorage
and increment the metric.
Since there is nothing user can do with this, in opposite to parsing
errors or bad timestamps, there is not much sense in incrementing this
metric. So this commit rolls-back `reason="nan_value"` increments.
