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

InstanceSpec struct members are untyped integers, so they can overflow
on 32-bit arch when bit-shifted left.

This commit introduces a new metric to count the number of failed
requests to Linode's API when using Linode SD. Resolves#10672, inspired
by #10476.
_Note_: this doens't count failures when polling the `/account/events`
endpoint, as a `401` there is how we determine if the supplied token has
the needed API scopes to do event polling vs full refreshes each
interval.

We are re-enabling HTTP 2 again. There has been a few bugfixes upstream
in go, and we have also enabled ReadIdleTimeout.

* optimize Linode SD by polling for event changes during refresh
Most accounts are fairly "static", in the sense that they're not cycling
through instances constantly. So rather than do a full refresh every
interval and potentially make several behind-the-scenes paginated API
calls, this will now poll the `/account/events/` endpoint every minute
with a list of events that we care about. If a matching event is found,
we then do a full refresh.
