* labels: respect Set after Del in Builder (#12322)
The implementations are not symmetric between `Set()` and `Del()`, so
we must be careful. Add tests for this, both in labels and in relabel
where the issue was reported.
Also make the slice implementation consistent re `slices.Contains`.
* Create v2.43.1 with bugfix

This change introduces a new variable, SANITIZED_DOCKER_IMAGE_TAG, which
replaces any '+' characters in the original DOCKER_IMAGE_TAG with '_'
characters. This ensures better compatibility with semver standards,
particularly when using metadata in version tags.

Although we had a different slice, the underlying memory was the same so
any changes meant we could skip some values.

Scraping targets are synced by creating the full set, then adding/removing any which have changed.
This PR speeds up the process of creating the full set.
I added a benchmark for `TargetsFromGroup`; it uses configuration from a typical Kubernetes SD.
The crux of the change is to do relabeling inside labels.Builder instead of converting to labels.Labels and back again for every rule. The change is broken into several commits for easier review.
This is a breaking change to `scrape.PopulateLabels()`, but `relabel.Process` is left as-is, with a new `relabel.ProcessBuilder` option.
In storage/remote, try converting to RecoverableError using errors.As,
instead of through direct casting.

TestConcurrentRangeQueries runs many queries, up to 4 at the same time,
to try to expose any race conditions.
This change stops four of them from running with a thousand or more steps:
`holt_winters(a_X[1d], 0.3, 0.3)`
`changes(a_X[1d])`
`rate(a_X[1d])`
`absent_over_time(a_X[1d])`
Particularly when the test runs with `-race` in CI, this reduces the
time and resources required.

Common service discovery mechanisms such as Kubernetes can generate a
lot of target groups, so this function was allocating a lot of memory
which then immediately became garbage. Re-using the structures across
an entire Sync saves effort.

Save work converting to `Labels` then to `Builder`.
`PopulateLabels()` now takes as Builder as input.

Save work converting between Builder and Labels.
Also expose ProcessBuilder, so callers can supply a Builder.

This lets relabelling work on a `Builder` rather than converting to and
from `Labels` on every rule.

Adds `WALReplayConcurrency` as an option on tsdb `Options` and `HeadOptions`.
If it is not set or set <=0, then `GOMAXPROCS` is used, which matches the previous behaviour.

The difference is modest, but we've used `slices.Sort` in lots of other
places so why not here.
