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.

ee1f3414d1 app/vmselect/promql: do not override [d] at last_over_time(m[d]) if [d] is smaller than scrape_interval

5d92fafc40 app/vmselect: add -search.noStaleMarkers command-line flag for disabling stale markers handling in queries 
This option allows reducing CPU usage a bit when VictoriaMetrics is used
for collecting and processing non-Prometheus data. For example, InfluxDB line protocol, Graphite, OpenTSDB, CSV, etc.

It is better to remove staleness marks (decimal.StaleNaN) before calling rollupConfig.Do, e.g. in preFunc

af4a306d7b app/vmselect/promql: properly handle Prometheus staleness marks in removeCounterResets functions 
Prometheus stalenss marks shouldn't be changed in removeCounterResets. Otherwise they will be converted to an ordinary NaN values,
which couldn't be removed in dropStaleNaNs() function later. This may result in incorrect calculations for rollup functions.

* Rename -search.maxMetricsPointSearch to -search.maxSamplesPerQuery, so it is more consistent with the existing -search.maxSamplesPerSeries
* Move the -search.maxSamplesPerQuery from vmstorage to vmselect, so it could effectively limit the number of raw samples obtained from all the vmstorage nodes
* Document the -search.maxSamplesPerQuery in docs/CHANGELOG.md

- Support durations without suffix. E.g. rate(m[300]) is equivalent to rate(m[5m])

a15c947045 promql: fix increase_pure calculation for cases with stale series (#1381) 
Due to staleness handling, increase_pure were using incorrect previous value
during calculation in cases where series disappears for period longer
than staleness period and then returns back. The fix suppose to account
for a real datapoint value before staleness takes place. The fix should
remove unexpected spikes while using `increase_pure` for staled series.
