lib/promscrape: use the standard net/http.Client instead of fasthttp.Client for scraping targets in non-streaming mode 
While fasthttp.Client uses less CPU and RAM when scraping targets with small responses (up to 10K metrics),
it doesn't work well when scraping targets with big responses such as kube-state-metrics.
In this case it could use big amounts of additional memory comparing to net/http.Client,
since fasthttp.Client reads the full response in memory and then tries re-using the large buffer
for further scrapes.

Additionally, fasthttp.Client-based scraping had various issues with proxying, redirects
and scrape timeouts like the following ones:

- https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1945
- https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5425
- https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2794
- https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1017

This should help reducing memory usage for the case when target returns big response
and this response is scraped by fasthttp.Client at first before switching to stream parsing mode
for subsequent scrapes. Now the switch to stream parsing mode is performed on the first scrape
after reading the response body in memory and noticing that its size exceeds the value passed
to -promscrape.minResponseSizeForStreamParse command-line flag.

lib/pushmetrics: wait until the background goroutines, which push metrics, are stopped at pushmetrics.Stop() 
Previously the was a race condition when the background goroutine still could try collecting metrics
from already stopped resources after returning from pushmetrics.Stop().
Now the pushmetrics.Stop() waits until the background goroutine is stopped before returning.

This is a follow-up for https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5549
and the commit fe2d9f6646 .

app/vmselect/promql: add drop_empty_series() function for dropping empty series before performing additional calculations 
This can be useful in the following queries:

   drop_empty_series(temperature <= 30) default 40

This query drops temperature series with all the values bigger than 30 on the selected time range,
while replacing gaps in the remaining series with 40.

The query without drop_empty_series:

  (temperature <= 30) default 40

would leave all the temperature series with all the values bigger than 30 on the selected time range,
and replace all their values with 40. This is not what could be epxected in some cases

app/vmselect/promql: add the ability to copy all the labels from one side of group_left()/group_right() operation 
This is performed by specifying `*` inside group_left()/group_right().
Also allow specifying prefix for the copied labels via `group_left(...) prefix "..."` and `group_right(...) prefix "..."` syntax.
For example, the following query adds all the namespace-related labels to pod info, and prefixes all the copied label names with "ns_" prefix:

  kube_pod_info * on(namespace) group_left(*) prefix "ns_" kube_namespace_labels

This resolves the following StackOverflow questions:

app/vmselect/promql: recommend to use (a op b) keep_metric_names instead of a op b keep_metric_names 
The `a op b keep_metric_names` is ambigouos to `a op (b keep_metric_names)` when `b` is a transform or rollup function.
For example, `a + rate(b) keep_metric_names`. So it is better to use more clear syntax: `(a op b) keep_metric_names`

all: add support for or filters in series selectors 
This commit adds ability to select series matching distinct filters via a single series selector.
For example, the following selector selects series with either {env="prod",job="a"}
or {env="dev",job="b"} labels:

  {env="prod",job="a" or env="dev",job="b"}

The `or` filter is supported in all the VictoriaMetrics tools now.
