e894a22b88 feat: add config label to refresh metrics
Adds a `config` label (similar to `prometheus_sd_discovered_targets`) to
refresh metrics to help identify the source of refresh issues or
performance stats. In particular for HTTP SD, it can be common to have
multiple disparate HTTP SD sources that should be identified and not
lumped together. For example if one HTTP SD service has failures, that
should be evident in its own time series seperate from other HTTP SD
sources.

`config` seemed more appropriate than `endpoint` as a general standard
for `prometheus_sd` metrics.

Docs were also updated for HTTP SD to point at the new refresh metrics
rather than the older metrics.

747c5ee2b1 Apply analyzer "modernize" to the whole codebase
See
https://pkg.go.dev/golang.org/x/tools/gopls/internal/analysis/modernize
for details.

This ran into a few issues (arguably bugs in the modernize tool),
which I will fix in the next commit, so that we have transparency what
was done automatically.

Beyond those hiccups, I believe all the changes applied are
legitimate. Even where there might be no tangible direct gain, I would
argue it's still better to use the "modern" way to avoid micro
discussions in tiny style PRs later.

6ebfbd2d54 chore!: adopt log/slog, remove go-kit/log
For: #14355

This commit updates Prometheus to adopt stdlib's log/slog package in
favor of go-kit/log. As part of converting to use slog, several other
related changes are required to get prometheus working, including:
- removed unused logging util func `RateLimit()`
- forward ported the util/logging/Deduper logging by implementing a small custom slog.Handler that does the deduping before chaining log calls to the underlying real slog.Logger
- move some of the json file logging functionality to use prom/common package functionality
- refactored some of the new json file logging for scraping
- changes to promql.QueryLogger interface to swap out logging methods for relevant slog sugar wrappers
- updated lots of tests that used/replicated custom logging functionality, attempting to keep the logical goal of the tests consistent after the transition
- added a healthy amount of `if logger == nil { $makeLogger }` type conditional checks amongst various functions where none were provided -- old code that used the go-kit/log.Logger interface had several places where there were nil references when trying to use functions like `With()` to add keyvals on the new *slog.Logger type
