with label values for the specified focusLabel, which contain the highest number of time series.

- Remove unused js bloatware from /targets page. This strips down binary size by more than 100Kb
- Add /service-discovery page for API compatibility with Prometheus
- Properly load bootstrap.min.css from /prometheus/targets
- Serve static contents for /targets page from app/vminsert instead of app/vmselect, because /targets page is served from there

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: 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: de-duplicate data exported via /api/v1/export/csv by default 
Previously the exported data wasn't de-duplicated.
Now it is possible to export the raw data without deduplication
by passing reduce_mem_usage=1 query arg to /api/v1/export/csv
