Ondrej Kokes 2e30f1231b docs: textparse.Parser return type mismatch 
The docs suggest the Next method returns a bool, but that's not the case (`Entry` is an int).

```
	// Next advances the parser to the next sample. It returns false if no
	// more samples were read or an error occurred.
	Next() (Entry, error)
```

The docs were first added in d80a3de235 in 2017. Back then the signature was
indeed `func (p *Parser) Next() bool`. But then it got refactored in 76a4a46cb0
and the signature changed with it, yet docs stayed the same - and eventually made their way into the `Parser` interface.

However, the Protobuf parser does have the right wording: 5de2df752f

```
// Next advances the parser to the next "sample" (emulating the behavior of a
// text format parser). It returns (EntryInvalid, io.EOF) if no samples were
// read.
```

Changing all other implementations (and the interface itself) to match this doc.

storage/remote: disable resharding during active retry backoffs (#13562) 
* storage/remote: disable resharding during active retry backoffs

Today, remote_write reshards based on pure throughput. This is
problematic if throughput has been diminished because of HTTP 429s;
increasing the number of shards due to backpressure will only exacerbate
the problem.

This commit disables resharding for twice the retry backoff, ensuring
that resharding will never occur during an active backoff, and that
resharding does not become enabled again until enough time has elapsed
to allow any pending requests to be retried.

* storage/remote: address review feedback

Signed-off-by: Robert Fratto <robertfratto@gmail.com>

* storage/remote: track time where resharding initially got disabled

This change introduces a second atomic int64 to roughly track when
resharding got disabled. This int64 is only updated after updating the
disabled timestamp if resharding was previously enabled.

Łukasz Mierzwa 21f8b35f5b Move staleness tracking out of checkAddError() calls 
This call bloats checkAddError signature and logic, we can and should call it from the main scrape logic.

Łukasz Mierzwa 55dcaab41b Fix TestScrapeLoopDiscardDuplicateLabels test 
This test calls Rollback() which is normally called from within append code.
Doing so means that staleness tracking data is outdated and need to by cycled manually.

Łukasz Mierzwa 50c81bed86 Check for duplicated series on a scrape 
When Prometheus scrapes a target and it sees the same time series repeated multiple times it currently silently ignores that.
This change adds a test for that and fixes the scrape loop so that:

- Only first sample for each unique time series is appended
- Duplicated samples increment the prometheus_target_scrapes_sample_duplicate_timestamp_total metric

This allows one to identify such scrape jobs and targets.

Benchmark results:

Łukasz Mierzwa 1a8ea78207 Fix BenchmarkScrapeLoopAppendOM 
OpenMetrics requires EOF comment at the end of metrics body, but the makeTestMetrics() function doesn't append it.
This means this benchmark tests a response with errors but I don't think that was the intention.
