lib/promrelabel: speedup label match by __name__ ( #6432 )
...
The change adds a fastpath for `equalValue` comparisons against
`__name__` label by avoiding calls to `toCanonicalLabelName` func. This
speedups matches by metric name like `'foo'`. See bench stats below:
```
benchcmp old.txt new.txt
benchmark old ns/op new ns/op delta
BenchmarkIfExpression/equal_label:_last-10 35.6 35.1 -1.18%
BenchmarkIfExpression/equal_label:_middle-10 18.3 17.3 -5.41%
BenchmarkIfExpression/equal_label:_first-10 1.20 1.24 +2.74%
BenchmarkIfExpression/equal___name__:_last-10 10.1 4.96 -50.75%
BenchmarkIfExpression/equal___name__:_middle-10 5.79 3.16 -45.41%
BenchmarkIfExpression/equal___name__:_first-10 1.17 1.05 -9.76%

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/promrelabel: optimize matching for commonly used regex patterns in if option
...
The following regex patterns are optimized:
- literal string match, e.g. "foo"
- prefix match, e.g. "foo.*" and "foo.+"
- substring match, e.g. ".*foo.*" and ".+foo.+"
- alternate values match, e.g. "foo|bar|baz"

lib/promscrape: properly implement ScrapeConfig.clone()
...
Previously ScrapeConfig.clone() was improperly copying promauth.Secret fields -
their contents was replaced with `<secret>` value.
This led to inability to use passwords and secrets in `-promscrape.config` file.
The bug has been introduced in v1.77.0 in the commit 67b10896d2https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2551
