lib/promscrape/discovery/gce: follow-up for b2ccdaaa2f
- Use promutils.Labels.GetLabels() instead of comparing promutils.Labels.Labels to nil.
  This make the code more consistent with other places.

- Mention the release where the issue has been introduced at docs/CHANGELOG.md.

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.

lib/promscrape: optimize discoveryutils.SanitizeLabelName()
Cache sanitized label names and return them next time.
This reduces the number of allocations and speeds up the SanitizeLabelName()
function for common case when the number of unique label names is smaller than 100k

all: subsitute ioutil.ReadAll with io.ReadAll
ioutil.ReadAll is deprecated since Go1.16 - see https://tip.golang.org/doc/go1.16#ioutil
VictoriaMetrics requires at least Go1.18, so it is OK to switch from ioutil.ReadAll to io.ReadAll.

This is a follow-up for 02ca2342ab

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 67b10896d2
