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

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.

use ?wait=10m will give results as fast as usual when data is changing
but will perform far less requests when services do not change.
On large infrastructure, this will reduce quite a lot the number of
qps on Consul servers while having the same performance for freshness
of results.

i) Uses the more idiomatic Wrap and Wrapf methods for creating nested errors.
ii) Fixes some incorrect usages of fmt.Errorf where the error messages don't have any formatting directives.
iii) Does away with the use of fmt package for errors in favour of pkg/errors
