Add basic initial developer docs for TSDB (#9451)
* Add basic initial developer docs for TSDB

There's a decent amount of content already out there (blog posts,
conference talks, etc), but:
* when they get stale, they don't tend to get updated
* they still leave me with questions that I'ld like to answer
  for developers (like me) who want to use, or work with, TSDB

What I propose is developer docs inside the prometheus
repository.  Easy to find and harness the power of the community
to expand it and keep it up to date.

* perfect is the enemy of good.  Let's have a base and incrementally improve
* Markdown docs should be broad but not too deep.  Source code comments
  can complement them, and are the ideal place for implementation details.

discovery/kubernetes: improve test logic for waiting for discoverers (#9584)
When running tests in parallel, 10 milliseconds may not be enough for
all discoverers to register, which will make test flaky.

This commit changes the waiting logic to wait for number of discoverers
to stop increasing during given time frame, which should be large enough
for single discoverer to register in test environment.

A following run passes with this commit:

go test -failfast -race -count 100 -v ./discovery/kubernetes/

We have been Puppet user for 10 years and we are users of
https://github.com/camptocamp/prometheus-puppetdb-sd

However, that file_sd implementation contains business logic and
assumptions around e.g. the modules which you are using.

This pull request adds a simple PuppetDB service discovery, which will
enable more use cases than the upstream sd.

Merge release 2.29 in main (#9196)
* PromQL: Fix start and end keywords masking label and metric names

This commit fixes an issue with the "at modifier" that introduced two
new keywords: `start` and `end`. In grouping options and in metric
names, these keywords took precedence over metric or label names, so
that those metrics and labels could no longer be referenced.

optimize Linode SD by polling for event changes during refresh (#8980)
* optimize Linode SD by polling for event changes during refresh

Most accounts are fairly "static", in the sense that they're not cycling
through instances constantly. So rather than do a full refresh every
interval and potentially make several behind-the-scenes paginated API
calls, this will now poll the `/account/events/` endpoint every minute
with a list of events that we care about. If a matching event is found,
we then do a full refresh.
