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.

app/vmselect/prometheus: reduce the default value for -search.maxSeries from 100k to 30k 
Production experience shows that 100k is too big for /api/v1/series .
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.

lib/storage: return marshaled metric names from SearchMetricNames 
Previously SearchMetricNames was returning unmarshaled metric names.
This wasn't great for vmstorage, which should spend additional CPU time
for marshaling the metric names before sending them to vmselect.

While at it, remove possible duplicate metric names, which could occur when
multiple samples for new time series are ingested via concurrent requests.

Also sort the metric names before returning them to the client.
This simplifies debugging of the returned metric names across repeated requests to /api/v1/series

vmselect: limit end param max value by 2d in future (#2729) 
* vmselect: limit `end` param max value by 2d in future

The change is applied only to service handlers like `/labels` or `/series`
and limits the `end` param by max value <= now() + 2 days. The same limit
is applied for the ingested data, so no reason to allow to request data
in future far than that.

The change is also needed for corner cases like https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2669
where too high `end` value triggers inefficient global index search.

Export "null" in jsonl instead of NaN (#2518) 
* Export "null" in jsonl instead of NaN

The NaN appeared because of staleness markers that were added for compatibility. I think it's better to use json `null`, implemented here.

Also maybe it also makes sense to add a flag like `?skip-staleness-markers=true` to `/export`, to skip nulls at all?

lib/bytesutil: split Resize() into ResizeNoCopy() and ResizeWithCopy() functions 
Previously bytesutil.Resize() was copying the original byte slice contents to a newly allocated slice.
This wasted CPU cycles and memory bandwidth in some places, where the original slice contents wasn't needed
after slize resizing. Switch such places to bytesutil.ResizeNoCopy().

Rename the original bytesutil.Resize() function to bytesutil.ResizeWithCopy() for the sake of improved readability.

Additionally, allocate new slice with `make()` instead of `append()`. This guarantees that the capacity of the allocated slice
exactly matches the requested size. The `append()` could return a slice with bigger capacity as an optimization for further `append()` calls.
This could result in excess memory usage when the returned byte slice was cached (for instance, in lib/blockcache).

app/vmselect/promql: properly keep metric names when optimized path is used for aggregate function calculations 
For example, `sum(rate(...) keep_metric_names) by (__name__)` didn't leave the original metric name because of this issue.

app/vmselect/promql: add support for @ modifier 
Add support for `@` modifier in MetricsQL according to https://prometheus.io/docs/prometheus/latest/querying/basics/#modifier

Extend the support with the following features:
* Allow using `@` modifier everywhere in the query. For example, `sum(foo) @ end()`
* Allow using arbitrary expression as `@` modifier. For example, `foo @ (end() - 1h)`
  returns `foo` value at `end - 1 hour` timestamp on the selected time range `[start ... end]`

app/vmselect/promql: return back the behaviour for deriv() function when the lookbehind window doesnt contain enough points 
It is expected that the `deriv(m[d])` returns non-empty value if the lookbehind window `d`
contains less than 2 samples in the same way as `rate()` does.

This is a follow-up after 3e084be06b .

app/vmselect: make predict_linear and deriv compatible with Prometheus (#1681) 
Previously, `predict_linear` returned slightly different results comparing
to Prometheus. The change makes linear regression algorithm compatible
with Prometheus.

`deriv` was excluded from the list of functions which can adjust the time
window for the same reasons.

app/vmselect: quantile func compatiblity with Prometheus (#1646) 
* app/vmselect: `quantile` func compatiblity with Prometheus

The `quantile` func was previously calculated by https://github.com/valyala/histogram
package. The result of such calculation was always the closest real value to
requested quantile. While in Prometheus implementation interpolation is used.
Such difference may result into discrepancy in output between Prometheus and
VictoriaMetrics.

This commit adds a Prometheus-like `quantile` function. It also used by other
functions which depend on it, such as `quantiles`, `quantile_over_time`, `median` etc.

- Do not save server url to persistent storage at browser, since it should be always obtained from the url.

Before, metric `vm_request_duration_seconds` was update only on successful

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.
