Just adding a statement here explaining that the default is an
immediate move to "active" without a pending state.

This is a minor cosmetical change, but my IDE (and I guess many of them)
nests `labels_string.go` under `labels.go` because it assumes it's the
file generated by the `stringer` tool, which follows that naming
pattern.

* add alert for sd refresh failure
Due to config error or sd service down, prometheus may fail to refresh sd resource, which may lead to scrape fail or irrelavant metrics.

I had changed the naming from "jitter" to "offset" in:
cb045c0e4b
...but I forgot to add this file to the commit to complete the renaming,
doing that now.

Using github.com/klauspost/compress package to replace the current Gzip Handler on the API.
We see significant improvements using this handler over the current one as shown in the benchmark added.
Also:
* move selection of compression from `newCompressedResponseWriter` to `*CompressionHandler.ServeHTTP`.
* renaming `compressedResponseWriter` since it now only does one kind of compression.

Adds web config option `client_allowed_sans`. This enables Prometheus to
limit the Subject Alternate Name (SAN) allowed to connect.

As the 2.37 LTS is going EOL in July 2023, let's mark 2.45 as LTS. I
have synced with Jesus about this. He will bootstrap the release and
after a few week I will do the maintenance for the lifetime of the LTS.

In digital communication, "jitter" usually refers to how much a signal deviates
from true periodicity, see https://en.wikipedia.org/wiki/Jitter. The way we are
using the "jitterSeed" in Prometheus does not affect the true periodicity at
all, but just introduces a constant phase shift (or offset) within the period.
So it would be more correct and less confusing to call the "jitterSeed" an
"offsetSeed" instead.

Use AppendableGauge to detect corrupt chunk with gauge histograms.
Detect if first sample is a gauge but the chunk is not set up to contain
gauge histograms.

Problem:
LabelValueStats - This will provide a list of the label names and memory used in bytes.
It is calculated by adding the length of all values for a given label name.
But internally Prometheus stores the name and the value independently for each series.
Solution:
MemPostings struct maintains the values to seriesRef map which is used
to get the number of series which contains the label values.
Using that LabelValueStats is calculated as: seriesCnt * len(value
name)
