We still need a guide that we can link users to in https://github.com/prometheus/docs/tree/main/content/docs/guides
This guide should show sending metrics from application directly via
the OTel SDKs and also sending through the Collector.

* Add OTLP Ingestion endpoint
We copy files from the otel-collector-contrib. See the README in
`storage/remote/otlptranslator/README.md`.
This supersedes: https://github.com/prometheus/prometheus/pull/11965

* Return a 200 OK
It is what the OTEL Golang SDK expect :(

Adds a new label to include the ID of the image that an instance is
using. This can be used for example to filter a job to only include
instances using a certain image as that image includes some exporter.
Sometimes the image information isn't available, such as when the image
is private and the user doesn't have the roles required to see it. In
those cases we just don't set the label, as the rest of the information
from the discovery provider can still be used.

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

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

Handle more arithmetic operators and aggregators for native histograms
This includes operators for multiplication (formerly known as scaling), division, and subtraction. Plus aggregations for average and the avg_over_time function.
Stdvar and stddev will (for now) ignore histograms properly (rather than counting them but adding a 0 for them).

So far, if a target exposes a histogram with both classic and native
buckets, a native-histogram enabled Prometheus would ignore the
classic buckets. With the new scrape config option
`scrape_classic_histograms` set, both buckets will be ingested,
creating all the series of a classic histogram in parallel to the
native histogram series. For example, a histogram `foo` would create a
native histogram series `foo` and classic series called `foo_sum`,
`foo_count`, and `foo_bucket`.
This feature can be used in a migration strategy from classic to
native histograms, where it is desired to have a transition period
during which both native and classic histograms are present.
Note that two bugs in classic histogram parsing were found and fixed
as a byproduct of testing the new feature:
1. Series created from classic _gauge_ histograms didn't get the
_sum/_count/_bucket prefix set.
2. Values of classic _float_ histograms weren't parsed properly.
