Combine Appender.Add and AddFast into a single Append method. (#8489)
This moves the label lookup into TSDB, whilst still keeping the cached-ref optimisation for repeated Appends.

This makes the API easier to consume and implement.  In particular this change is motivated by the scrape-time-aggregation work, which I don't think is possible to implement without it as it needs access to label values.

Tom Wilkie d479151f1f Various enhancements and refactorings for remote write receiver:
- 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

'@ <timestamp>' modifier (#8121)
This commit adds `@ <timestamp>` modifier as per this design doc: https://docs.google.com/document/d/1uSbD3T2beM-iX4-Hp7V074bzBRiRNlqUdcWP6JTDQSs/edit.

An example query:

```
rate(process_cpu_seconds_total[1m]) 
  and
topk(7, rate(process_cpu_seconds_total[1h] @ 1234))
```

which ranks based on last 1h rate and w.r.t. unix timestamp 1234 but actually plots the 1m rate.

beorn7 0f3c1bf6cf Report valid configs in the respective metrics from the beginning
In #7399, an early validity check of the config was introduced to
prevent the scenario where an invalid config is only detected after a
possibly very long startup procedure. However, the respective success
metrics are not updated after the initial validation so that the
success metrics suggest an invalid config. If the startup procedure,
like replaying the WAL, really takes very long, alerts about invalid
config will trigger.

This commit sets the succes metrics after initial validation. They
will be set again after the "real" config (re-)load, but that
shouldn't be a problem. The metric now truthfully represents whenever
the config was successfully loaded, no matter if the result was then
thrown away (because it was just for validation) or actually used.

promql: Removed global and add ability to have better interval for subqueries if not specified (#7628)
* promql: Removed global and add ability to have better interval for subqueries if not specified

## Changes
* Refactored tests for better hints testing
* Added various TODO in places to enhance.
* Moved DefaultEvalInterval global to opts with func(rangeMillis int64) int64 function instead

Motivation: At Thanos we would love to have better control over the subqueries step/interval.
This is important to choose proper resolution. I think having proper step also does not harm for
Prometheus and remote read users. Especially on stateless querier we do not know evaluation interval
and in fact putting global can be wrong to assume for Prometheus even.

I think ideally we could try to have at least 3 samples within the range, the same
way Prometheus UI and Grafana assumes.

Anyway this interfaces allows to decide on promQL user basis.

Open question: Is taking parent interval a smart move?

Motivation for removing global: I spent 1h fighting with:


=== RUN   TestEvaluations
    TestEvaluations: promql_test.go:31: unexpected error: error evaluating query "absent_over_time(rate(nonexistant[5m])[5m:])" (line 687): unexpected error: runtime error: integer divide by zero
--- FAIL: TestEvaluations (0.32s)
FAIL

At the end I found that this fails on most of the versions including this master if you run this test alone. If run together with many
other tests it passes. This is due to SetDefaultEvaluationInterval(1 * time.Minute)
in test that is ran before TestEvaluations. Thanks to globals (:

Let's fix it by dropping this global.

* Queryable client is now SampleAndChunkQueryable. Since we cannot use nice QueryableFunc I moved
all config based options to sampleAndChunkQueryableClient to aboid boilerplate.

M-map full chunks of Head from disk (#6679)
When appending to the head and a chunk is full it is flushed to the disk and m-mapped (memory mapped) to free up memory

Prom startup now happens in these stages
 - Iterate the m-maped chunks from disk and keep a map of series reference to its slice of mmapped chunks.
- Iterate the WAL as usual. Whenever we create a new series, look for it's mmapped chunks in the map created before and add it to that series.

If a head chunk is corrupted the currpted one and all chunks after that are deleted and the data after the corruption is recovered from the existing WAL which means that a corruption in m-mapped files results in NO data loss.

[Mmaped chunks format](https://github.com/prometheus/prometheus/blob/master/tsdb/docs/format/head_chunks.md)  - main difference is that the chunk for mmaping now also includes series reference because there is no index for mapping series to chunks.
[The block chunks](https://github.com/prometheus/prometheus/blob/master/tsdb/docs/format/chunks.md) are accessed from the index which includes the offsets for the chunks in the chunks file - example - chunks of series ID have offsets 200, 500 etc in the chunk files.
In case of mmaped chunks, the offsets are stored in memory and accessed from that. During WAL replay, these offsets are restored by iterating all m-mapped chunks as stated above by matching the series id present in the chunk header and offset of that chunk in that file.

**Prombench results**

_WAL Replay_

1h Wal reply time
30% less wal reply time - 4m31 vs 3m36
2h Wal reply time
20% less wal reply time - 8m16 vs 7m

_Memory During WAL Replay_

High Churn:
10-15% less RAM -  32gb vs 28gb
20% less RAM after compaction 34gb vs 27gb
No Churn:
20-30% less RAM -  23gb vs 18gb
40% less RAM after compaction 32.5gb vs 20gb

Bartlomiej Plotka 34426766d8 Unify Iterator interfaces. All point to storage now.
This is part of https://github.com/prometheus/prometheus/pull/5882 that can be done to simplify things.
All todos I added will be fixed in follow up PRs.

* querier.Querier, querier.Appender, querier.SeriesSet, and querier.Series interfaces merged
with storage interface.go. All imports that.
* querier.SeriesIterator replaced by chunkenc.Iterator
* Added chunkenc.Iterator.Seek method and tests for xor implementation (?)
* Since we properly handle SelectParams for Select methods I adjusted min max
based on that. This should help in terms of performance for queries with functions like offset.
* added Seek to deletedIterator and test.
* storage/tsdb was removed as it was only a unnecessary glue with incompatible structs.

No logic was changed, only different source of abstractions, so no need for benchmarks.

Julien Pivotto 9adad8ad30 Remove MaxConcurrent from the PromQL engine opts (#6712)
Since we use ActiveQueryTracker to check for concurrency in
d992c36b3a it does not make sense to keep
the MaxConcurrent value as an option of the PromQL engine.

This pull request removes it from the PromQL engine options, sets the
max concurrent metric to -1 if there is no active query tracker, and use
the value of the active query tracker otherwise.

It removes dead code and also will inform people who import the promql
package that we made that change, as it breaks the EngineOpts struct.

*: avoid missed Alertmanager targets (#6455)
This change makes sure that nearly-identical Alertmanager configurations
aren't merged together.

The config's identifier was the MD5 hash of the configuration serialized
to JSON but because `relabel.Regexp` has no public field and doesn't
implement the JSON.Marshaler interface, it was always serialized to
"{}".

In practice, the identifier can be based on the index of the
configuration in the list.

In an effort to reduce confusion with the `m` option of the
`ParseDuration()` function, this commit adds the available time units to
the `storage.tsdb.retention.time` flag to help showcase that there is no
option for months (which could be assumed to be `m`).

If someone were looking to set the retention to six months, they may
mistakenly do so with `6m`, which would reduce their retention to six
minutes.

* Added query logging for prometheus.
Options added:
1) active.queries.filepath: Filename where queries will be recorded
2) active.queries.filesize: Size of the file where queries will be recorded.

Functionality added:
All active queries are now logged in a file. If prometheus crashes unexpectedly, these queries are also printed out on stdout in the rerun.

Queries are written concurrently to an mmaped file, and removed once they are done. Their positions in the file are reused. They are written in json format. However, due to dynamic nature of application, the json has an extra comma after the last query, and is missing an ending ']'. There may also null bytes in the tail of file.

Callum Styan 6f69e31398 Tail the TSDB WAL for remote_write
This change switches the remote_write API to use the TSDB WAL.  This should reduce memory usage and prevent sample loss when the remote end point is down.

We use the new LiveReader from TSDB to tail WAL segments.  Logic for finding the tracking segment is included in this PR.  The WAL is tailed once for each remote_write endpoint specified. Reading from the segment is based on a ticker rather than relying on fsnotify write events, which were found to be complicated and unreliable in early prototypes.

Enqueuing a sample for sending via remote_write can now block, to provide back pressure.  Queues are still required to acheive parallelism and batching.  We have updated the queue config based on new defaults for queue capacity and pending samples values - much smaller values are now possible.  The remote_write resharding code has been updated to prevent deadlocks, and extra tests have been added for these cases.

As part of this change, we attempt to guarantee that samples are not lost; however this initial version doesn't guarantee this across Prometheus restarts or non-retryable errors from the remote end (eg 400s).

This changes also includes the following optimisations:
- only marshal the proto request once, not once per retry
- maintain a single copy of the labels for given series to reduce GC pressure

Other minor tweaks:
- only reshard if we've also successfully sent recently
- add pending samples, latest sent timestamp, WAL events processed metrics
