* Remove unneeded dependency on `numeral` package
* Properly parse numbers obtained from /api/v1/query_range according to
https://prometheus.io/docs/prometheus/latest/querying/api/#expression-query-result-formats
* Optimize updating processing the received data from /api/v1/query_range
* Make smoother zoom on `ctrl+scroll`
* Reduce the number of points received from /api/v1/query_range by 2x in order to reduce load on backend
* lib/promscrape: support prometheus-like duration in scrape configs
The change allows to specify duration values like `1d`, `1w`
for fields `scrape_interval`, `scrape_timeout`, etc.

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).

Grafana expects `data` in response to be a slice and logs an err
if it is not:
```
err="[]v1.ExemplarQueryResult: decode slice: expect [ or n, but found , error found in #0 byte of ...||..., bigger context ...||..."
```
