In case of {Prefer,Require}DualStack policies in Services, K8s will
create two `EndpointSlices` resources for each IP family address type
specified. This created duplicate targets.

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.

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 commit removes support for the following API versions:
* `discovery.k8s.io/v1beta1` API version of EndpointSlice (no longer
served as of v1.25).
* `networking.k8s.io/v1beta1` API version of Ingress (no longer served
as of v1.22).
Closes#12884

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.
