promql: return step as scrapeInterval when it can't be calculated (#2865)
The change allows to specify default value for `getScrapeInterval`
function when actual interval can't be calculated.

Before the change, function were returning `maxSilenceInterval` (5m)
in such cases, which may be not correct for instant queries processing.
The specific scenario where using `maxSilenceInterval` caused issues
is the following:
1. Series becomes stale;
2. Client (in this case vmalert) continues to request series every 15s;
3. Database returns empty results as expected;
4. But at some specific moment of time database returns datapoints from `now()-5m`,
because lookback window was extended to `maxSilenceInterval`.

app/vmselect/netstorage: optimize mergeSortBlocks function
- Use binary search instead of linear scan when locating the run of smallest timestamps
  in blocks with intersected time ranges. This should improve performance
  when merging blocks with big number of samples

- Skip samples with duplicate timestamps. This should increase query performance
  in cluster version of VictoriaMetrics with the enabled replication.

vmalert: deprecate alert's status link (#2840)
* vmalert: deprecate alert's status link

Deprecate alert's status link `/api/v1/<groupID>/<alertID>/status` in favour of
`api/v1/alerts?group_id=<group_id>&alert_id=<alert_id>"`.

The change was needed for simplifying logic in vmselect for proxying vmalert's requests.

The old alert's status link will be still supported for a few versions but will be removed in the future.

app/vmselect/prometheus: reduce the default value for -search.maxSeries from 100k to 30k

It leads to increased CPU usage when Grafana queries /api/v1/series over VictoriaMetrics
with big number of time series during auto-completion and when modifying template variables.
