State explicitely what kind of timestamps are expected for the
--min-time and --max-time options of promtool tsdb commands.
This is especially important for the dump-openmetrics command as users
could otherwise mistakenly think it would be in seconds, like the
OpenMetrics timestamps themselves.

* rulefmt: add tests with YAML aliases for Alert/Record/Expr
Altough somewhat discouraged in favour of using proper configuration
management tools to generate full YAML, it can still be useful in some
situations to use YAML anchors/aliases in rules.
The current implementation is however confusing: aliases will work
everywhere except on the alert/record name and expr
This first commit adds (failing) tests to illustrate the issue, the next
one fixes it. The YAML test file is intentionally filled with anchors
and aliases. Although this is probably not representative of a real-world
use case (which would have less of them), it errs on the safer side.

* rulefmt: support YAML aliases for Alert/Record/Expr
This fixes the use of YAML aliases in alert/recording rule names and
expressions. A side effect of this change is that the RuleNode YAML type is
no longer propagated deeper in the codebase, instead the generic Rule type
can now be used.

Add --ignore-unknown-fields that ignores unknown fields in rule group
files. There are lots of tools in the ecosystem that "like" to extend
the rule group file structure but they are currently unreadable by
promtool if there's anything extra. The purpose of this flag is so that
we could use the "vanilla" promtool instead of rolling our own.
Some examples of tools/code:

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

Resolved by dropping the UTF-8 feature flag and adding the
`auto-reload-config` feature flag.
For the new web ui pick all changes from `main`.
This change causes Prometheus to allow all UTF-8 characters in metric and label names.
This means that names that were previously invalid and would have been previously rejected will be allowed through.

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 `//`.
