It does nothing for standard Prometheus builds with -tags stringlabels,
but the check to see if labels are being replaced has a cost.

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.

It was crashing due to uninitialized metrics, and not terminating due to
incorrectly reading segment names.
We need to export `SetMetrics` to avoid the first problem.

When the exemplar type is an int, it incorrectly gets converted to a 0
when DoubleValue() is called on the exemplar. This adds a check to
ensure that the value is converted properly based on the type.

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

The specialized version of sample add to the ring:
func addH(s hSample, buf []hSample, r *sampleRing) []hSample
func addFH(s fhSample, buf []fhSample, r *sampleRing) []fhSample
already correctly copy histogram samples from the reused hReader, fhReader
buffers, but the generic version does not. This means that the
data is overwritten on the next read if the sample ring has seen histogram
and float samples at the same time and switched to generic mode.
The `genericAdd` function (which was commented anyway) is by now quite
different from the specialized functions so that this commit deletes
it.
