Bryan Boreham 3c7de69059 storage: allow re-use of iterators
Patterned after `Chunk.Iterator()`: pass the old iterator in so it
can be re-used to avoid allocating a new object.

(This commit does not do any re-use; it is just changing all the method
signatures so re-use is possible in later commits.)

Add out-of-order sample support to the TSDB (#11075)
* Introduce out-of-order TSDB support

This implementation is based on this design doc:
https://docs.google.com/document/d/1Kppm7qL9C-BJB1j6yb6-9ObG3AbdZnFUBYPNNWwDBYM/edit?usp=sharing

This commit adds support to accept out-of-order ("OOO") sample into the TSDB
up to a configurable time allowance. If OOO is enabled, overlapping querying
are automatically enabled.

Most of the additions have been borrowed from
https://github.com/grafana/mimir-prometheus/

Add a --lint flag to the promtool check rules and check config commands (#10435)
* Add a --lint flag to the promtool check rules and check config commands

Checking rules with promtool emits warnings in the case of duplicate rules.
These warnings do not result in a non-zero exit code and are difficult to
spot in CI environments. Additionally, checking for duplicates is closer
to a lint check rather than a syntax check.

This commit adds a --lint flag to commands which include checking rules.
The flag can be used to enable or disable certain linting options
and cause the execution to return a non-zero exit code in case
those options are not met.

We always track total samples queried and add those to the standard set
of stats queries can report.

We also allow optionally tracking per-step samples queried. This must be
enabled both at the engine and query level to be tracked and rendered.
The engine flag is exposed via a Prometheus feature flag, while the
query flag is set when stats=all.

zzehring 42628899b5 promtool: Add --syntax-only flag for check config
This commit adds a `--syntax-only` flag for `promtool check config`.
When passing in this flag, promtool will omit various file existence
checks that would cause the check to fail (e.g. the check would not
fail if `rule_files` files don't exist at their respective paths).

This functionality will allow CI systems to check the syntax of
configs without worrying about referenced files.

tsdb: Rework iterators (#9877)
- Pick At... method via return value of Next/Seek.
- Do not clobber returned buckets.
- Add partial FloatHistogram suppert.

Note that the promql package is now _only_ dealing with
FloatHistograms, following the idea that PromQL only knows float
values.

As a byproduct, I have removed the histogramSeries metric. In my
understanding, series can have both float and histogram samples, so
that metric doesn't make sense anymore.

As another byproduct, I have converged the sampleBuf and the
histogramSampleBuf in memSeries into one. The sample type stored in
the sampleBuf has been extended to also contain histograms even before
this commit.

TSDB: demistify SeriesRefs and ChunkRefs (#9536)
* TSDB: demistify seriesRefs and ChunkRefs

The TSDB package contains many types of series and chunk references,
all shrouded in uint types.  Often the same uint value may
actually mean one of different types, in non-obvious ways.

This PR aims to clarify the code and help navigating to relevant docs,
usage, etc much quicker.

Concretely:

* Use appropriately named types and document their semantics and
  relations.
* Make multiplexing and demuxing of types explicit
  (on the boundaries between concrete implementations and generic
  interfaces).
* Casting between different types should be free.  None of the changes
  should have any impact on how the code runs.
