* 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

The links fix makes the links point to the current version of the files,
e.g. the relase branch.

Reduce the use of the term `long-term`, when what we're really talking
about is remote clustered storage for increased capacity and durability.

As discussed generally consider SDs as unstable, as realistically they
are never going to be. Drop the words "experimental/beta" from most
places in the docs, as users are getting the wrong impression from this.
The only section that still aplies was the one on the default storage
directory so those docs seem obsolete.
We'll probably have a similar page on the new storage but we'll only
find out what caveats etc. we'll have to point out as we get people
reporting problems or notable behavior.
