Fixed wrongly handled not ready TSDB on web and API. (#7182)
* fix federate endpoint panic

Signed-off-by: yeya24 <yb532204897@gmail.com>

* Fixed all cases of not ready TSDB being wrongly handled.

* Fixed issue for federation.
* Ensured this will never happen again thanks to interfaces
* Fixes same issue for stats.
* Added tests for readiness.
* Fixed bug in stats. It was:
   status.MaxTime = db.Head().MaxTime()
   status.MinTime = db.Head().MaxTime()

Use .UTC everywhere we use time.Unix (#7066)
time.Unix attaches the local timezone, which can then
leak out (e.g. in the alert json). While this is harmless,
we should be consistent.

storage: Added Chunks{Queryable/Querier/SeriesSet/Series/Iteratable. Added generic Merge{SeriesSet/Querier} implementation. (#7005)
* storage: Added Chunks{Queryable/Querier/SeriesSet/Series/Iteratable. Added generic Merge{SeriesSet/Querier} implementation.

## Rationales:

In many places (e.g. chunk Remote read, Thanos Receive fetching chunk from TSDB), we operate on encoded chunks not samples.
This means that we unnecessary decode/encode, wasting CPU, time and memory.
This PR adds chunk iterator interfaces and makes the merge code to be reused between both seriesSets

I will make the use of it in following PR inside tsdb itself. For now fanout implements it and mergers.

All merges now also allows passing series mergers. This opens doors for custom deduplications other than TSDB vertical ones (e.g. offline one we have in Thanos).

## Changes

* Added Chunk versions of all iterating methods. It all starts in Querier/ChunkQuerier. The plan is that
Storage will implement both chunked and samples.
* Added Seek to chunks.Iterator interface for iterating over chunks.
* NewMergeChunkQuerier was added; Both this and NewMergeQuerier are now using generigMergeQuerier to share the code. Generic code was added.
* Improved tests.
* Added some TODO for further simplifications in next PRs.

Bartlomiej Plotka c4eefd1b3a storage: Removed SelectSorted method; Simplified interface; Added requirement for remote read to sort response.
This is technically BREAKING CHANGE, but it was like this from the beginning: I just notice that we rely in
Prometheus on remote read being sorted. This is because we use selected data from remote reads in MergeSeriesSet
which rely on sorting.

I found during work on https://github.com/prometheus/prometheus/pull/5882 that
we do so many repetitions because of this, for not good reason. I think
I found a good balance between convenience and readability with just one method.
Smaller the interface = better.

Also I don't know what TestSelectSorted was testing, but now it's testing sorting.

Peter Štibraný 318cd413fc Don't return error in ContextFromRequest function.
Previously it could return error if RemoteAddr didn't
have correct format, but since this field has no specified
format, that was little too strict.

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.

Brian Brazil 38d32e0686 Don't sort postings if we only have one block.
Sorting the heads postings can be quite slow.
We only need sorted series when merging with another
querier, so only sort then.
This will make big queries that only touch the head faster,
though queries that touch both the head and a block will still
be the same speed. This probably won't help much with graphing
unless the range is under an hour, however it should make most
recording rules faster.

Add gaurantee that remote read streaming produces sorted series.

PromQL benchmarks for histograms show only 2-3% improvement, but
they're only over 1k series.

Brian Brazil 767fa704b6 Load only some offsets into the symbol table into memory.
Rather than keeping the entire symbol table in memory, keep every nth
offset and walk from there to the entry we need. This ends up slightly
slower, ~360ms per 1M series returned from PostingsForMatchers which is
not much considering the rest of the CPU such a query would go on to
use.

Make LabelValues use the postings tables, rather than having
to do symbol lookups. Use yoloString, as PostingsForMatchers
doesn't need the strings to stick around and adjust the API
call to keep the Querier open until it's all marshalled.

Remove allocatedSymbols memory optimisation, we no longer keep all the
symbol strings in heap memory. Remove LabelValuesFor and LabelIndices,
they're dead code. Ensure we've still tests for label indices,
and add missing test that we can work with old V1 Format index files.

PostingForMatchers performance is slightly better, with a big drop in
allocation counts due to using yoloString for LabelValues:

However overall Select performance is down and involves more allocs, due to

It collapses metadata that is equal across all targets, and aggregates under the same metric name the ones that differ.

* Allow tests to be asserted on response length

Some tests e.g. limit on API responses, don't require an assertion on
equality.

This allows us to assert against response length instead of
equality.

This commit introduces several test cases for the current /targets/metadata API endpoint.

To achieve so, we use a mock of the metadataStore and inject it to the targets under test.

Currently, three success cases are covered: with a metric name, with a target matcher, and with both. As for the failure scenario, the one where we couldn't match against a particular metric is covered.

gotjosh 4bf9c6bb82 Allow targets to be injected as arguments when creating a testTargetRetriever
Previously, the struct `testTargetRetriever` had hardcoded active and dropped targets. This made it difficult to change the target information depending on the test case.

This change introduces a way to define them as arguments and pass it to a constructor for building. It lays a foundation for dynamically defining targets with various set of arguments to test different scenarios.

Tobias Guggenmos be2bcc50a2 Fix target metadata API for empty match_targets (#6303)
According to the documentation, the target metadata API accepts it,
if no value for match_target has been provided. This was not the case
in the implementation.

This commit make the API behave as described in the docs.
