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

Sidecar containers are a newish feature in k8s. They're implemented
similar to init containers but actually stay running and allow you to
delay startup of your application pod until the sidecar started (like
init containers always do).
This adds the ports of the sidecar container to the list of discovered
endpoint(slice), allowing you to target those containers as well.
The implementation is a copy of that of Pod discovery

This went under the radar because the utils are never called directly.
We usually marshall/unmarshal Configs as embeded in a struct using UnmarshalYAMLWithInlineConfigs/MarshalYAMLWithInlineConfigs
which bypasses Configs' custom UnmarshalYAML/MarshalYAML

Several things done here:
- Set `max-issues-per-linter` to 0 so that we actually see all linter
warnings and not just 50 per linter. (As we also set
`max-same-issues` to 0, I assume this was the intention from the
beginning.)
- Stop using the golangci-lint default excludes (by setting
`exclude-use-default: false`. Those are too generous and don't match
our style conventions. (I have re-added some of the excludes
explicitly in this commit. See below.)
- Re-add the `errcheck` exclusion we have used so far via the
defaults.
- Exclude the signature requirement `govet` has for `Seek` methods
because we use non-standard `Seek` methods a lot. (But we keep other
requirements, while the default excludes completely disabled the
check for common method segnatures.)
- Exclude warnings about missing doc comments on exported symbols. (We
used to be pretty adamant about doc comments, but stopped that at
some point in the past. By now, we have about 500 missing doc
comments. We may consider reintroducing this check, but that's
outside of the scope of this commit. The default excludes of
golangci-lint essentially ignore doc comments completely.)
- By stop using the default excludes, we now get warnings back on
malformed doc comments. That's the most impactful change in this
commit. It does not enforce doc comments (again), but _if_ there is
a doc comment, it has to have the recommended form. (Most of the
changes in this commit are fixing this form.)
- Improve wording/spelling of some comments in .golangci.yml, and
remove an outdated comment.
- Leave `package-comments` inactive, but add a TODO asking if we
should change that.
- Add a new sub-linter `comment-spacings` (and fix corresponding
comments), which avoids missing spaces after the leading `//`.

to show "targets groups update" starvation when the notifications queue is full and an Alertmanager
is down.
The existing `TestHangingNotifier` that was added in https://github.com/prometheus/prometheus/pull/10948 doesn't really reflect the reality as the SD changes are manually fed into `syncCh` in a continuous way, whereas in reality, updates are only resent every `updatert`.
The test added here sets up an SD manager and links it to the notifier. The SD changes will be triggered by that manager as it's done in reality.

Previously the metrics adapters for client-go were registered in an init function.
This resulted in clobbering default metrics providers when these packages are imported
into an application that leverages the default client-go metrics registry.
Instead, let's only register these adapters when requested.

This commit adds 2 new metadata labels for the endpointslice role:
* `__meta_kubernetes_endpointslice_endpoint_node_name`
* `__meta_kubernetes_endpointslice_endpoint_zone`
The latter is only present when the `discovery.k8s.io/v1` API group is
available.
I also updated the configuration doc and added an entry for the
`__meta_kubernetes_endpointslice_endpoint_hostname` label which was
missing.

This adds support for Consul's Catalog [List Services][^1] API's `filter`
parameter added in 1.14.x. This parameter grants the operator more
flexibility to do server-side filtering of the Catalog, before
Prometheus subscribes for updates. Operators can use this to improve
both the performance of Prometheus's Consul SD and reduce the impact of
enumerating large catalogs.
