Matt Hughes 5868e36d91 scraper: fix UTF-8 scraping header always sent with PrometheusText1.0.0
The `Accept` header should not include `escape=allow-utf-8` unless
explicitly requested.

Conveniently, there was already a test covering this header's value, it
just required updating so it also asserts that this value in the header
is not set in the cases we don't expect it to be set. I also converted
those tests into table tests to help make failures clearer.

bwplotka f44bba31b3 config: Remove validation GetScrapeConfigs; require using config.Load.
We should never modify (or even shallow copy) Config after config.Load;
added comments and modified GetScrapeConfigs to do so. For GetScrapeConfigs
the validation (even repeated) was likely doing writes (because global fields was 0). We GetScrapeConfigs concurrently
in tests and ApplyConfig causing test races. In prod there were
races but likelyt only to replace 0 with 0, so not too severe.

I removed validation since I don't see anyone using our config.Config without Load.
I had to refactor one test that was doing it, all others use yaml config.

Fixes #15538

When a remote-write is executed towards a host name that is resolved to multiple IP addresses, this PR introduces a possibility to force creation of new connections used for the remote-write request to a randomly chosen IP address from the ones corresponding to the host name. The default behavior remains unchanged, i.s., the IP address used for the connection creation remains the one chosen by Go.

This is an experimental feature, it is disabled by default.

TJ Hoplock 6ebfbd2d54 chore!: adopt log/slog, remove go-kit/log
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
