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.

lib/promscrape: optimize service discovery speed
...
- Return meta-labels for the discovered targets via promutils.Labels
instead of map[string]string. This improves the speed of generating
meta-labels for discovered targets by up to 5x.
- Remove memory allocations in hot paths during ScrapeWork generation.
The ScrapeWork contains scrape settings for a single discovered target.
This improves the service discovery speed by up to 2x.
