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?

* Update app/vmselect/prometheus/export.qtpl

* app/vmselect/prometheus/export.qtpl.go: `make quicktemplate-gen`

* docs/CHANGELOG.md: document the change

app/vmselect/netstorage: report vmstorage errors to vmselect clients even if partial responses are allowed
If a vmstorage is reachable and returns an application-level error to vmselect,
then such error must be returned to the caller even if partial responses are allowed,
since it usually means cluster mis-configuration.

Partial responses may be returned only if some vmstorage nodes are temporarily unavailable.

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).
