The new docs site will have syntax highlighting, so this adds language tags
to code boxes that are currently missing them. I didn't add `promql` as a
language yet since the highlighter doesn't support it yet, plus a lot of
the PromQL codeboxes in our docs aren't strictly valid PromQL, they are
more like multiple expressions listed in the same code box on multiple
lines. So I'm leaving that for sometime later.
In the HTTP API page, I moved the curl examples from the JSON codeboxes to
their own ones above the JSON output. I considered putting an "Output:"
text between the curl + JSON output, but I think the way it currently looks
without it is probably fine.
I also fixed a number of headings which were at the wrong level relative to
their nesting in the document.
I also removed `go` as a language from the Go template language examples,
because the Go template language isn't Go at all.
I also adjusted the indent on one codebox to be more reasonable (2 spaces
instead of 8).
And then finally, my editor made a bunch of whitespace changes
automatically, like removing trailing spaces.

Conflicts:
cmd/prometheus/main.go
docs/command-line/prometheus.md
docs/feature_flags.md
web/ui/build_ui.sh
web/web.go
Resolved by dropping the UTF-8 feature flag and adding the
`auto-reload-config` feature flag.
For the new web ui pick all changes from `main`.
Reword the section on what to do if major corruption happens. Users are
being confused by the existing wording and cherry-picking the meaning
from the single sentance about durability.

* clarify backup requirements for storage
After reading this (again) recently, I was under the impression that our backup strategy ("just throw Bacula at it") was just not good enough and that our backups were inconsistent. I filed [an issue internally][41627] about this because of that concern.
But reading a conversation with @SuperQ on IRC, I came under the impression that only the WAL files would be lost. This is an attempt at documenting this more clearly.

This is about native histograms (not yet supported) and staleness
markers (for which OpenMetrics support isn't even planned).

Since `/api/v1/write` is a mutating endpoint, we should still activate
the remote-write-receiver explicitly. But we should do it in the same
way as the other mutating endpoints, i.e. via a flag
`--web.enable-remote-write-receiver`.
This commit marks the feature flag as deprecated, i.e. it still works
but logs a warning on startup. This enables users to seamlessly
migrate. With the next minor release, we can start ignoring the
feature flag (but still warn a user that is trying to use it).

* promtool: backfill: allow configuring block duration
When backfilling large amounts of data across long periods of time, it
may in certain circumstances be useful to use a longer block duration to
increase the efficiency and speed of the backfilling process. This patch
adds a flag --block-duration-power to allow a user to choose the power N
where the block duration is 2^(N+1)h.

* backfill: add messages to tests for clarity
When someone new breaks a test, seeing "expected: false, got: true" is
really not useful. A nice message helps here.

* backfill: test long block durations
A test that uses a long block duration to write bigger blocks is added.
The check to make sure all blocks are the default duration is removed.

- Remove unrelated changes
- Refactor code out of the API module - that is already getting pretty crowded.
- Don't track reference for AddFast in remote write. This has the potential to consume unlimited server-side memory if a malicious client pushes a different label set for every series. For now, its easier and safer to always use the 'slow' path.
- Return 400 on out of order samples.
- Use remote.DecodeWriteRequest in the remote write adapters.
- Put this behing the 'remote-write-server' feature flag
- Add some (very) basic docs.
- Used named return & add test for commit error propagation
