67bc407747 lib/promscrape: reduce memory and CPU usage when Prometheus staleness tracking is enabled for metrics from deleted / disappeared scrape targets 
Store the scraped response body instead of storing the parsed and relabeld metrics.
This should reduce memory usage, since the response body takes less memory than the parsed and relabeled metrics.
This is especially true for Kubernetes service discovery, which adds many long labels for all the scraped metrics.

This should also reduce CPU usage, since the marshaling of the parsed
and relabeld metrics has been substituted by response body copying.

0c2284b95f vmalert: add flag disableAlertgroupLabel for disabling extra label added to series (#1534) 
The new label added in https://github.com/VictoriaMetrics/VictoriaMetrics/issues/611
may negatively impact deduplication in Alertmanager. The new flag supposed to give
an option to disable adding this label.

To enable flag just add `-disableAlertgroupLabel` to binary execution command.

1ccb77904b vmselect: update vm_request_duration_seconds value when request fails (#1537) 
Before, metric `vm_request_duration_seconds` was update only on successful
attempts which could be misleading. For example, timeout errors on netstorage
request may be not accounted in the metric and won't be visible on dashboards.
Using `defer` statement to update the metric after query arguments validation
may improve the situation.
