tsdb: Added ChunkQueryable implementations to db; unified MergeSeriesSets and vertical to single struct. (#7069)
* tsdb: Added ChunkQueryable implementations to db; unified compactor, querier and fanout block iterating.

Chained to https://github.com/prometheus/prometheus/pull/7059

* NewMerge(Chunk)Querier now takies multiple primaries allowing tsdb DB code to use it.
* Added single SeriesEntry / ChunkEntry for all series implementations.
* Unified all vertical, and non vertical for compact and querying to single
merge series / chunk sets by reusing VerticalSeriesMergeFunc for overlapping algorithm (same logic as before)
* Added block (Base/Chunk/)Querier for block querying. We then use populateAndTomb(Base/Chunk/) to iterate over chunks or samples.
* Refactored endpoint tests and querier tests to include subtests.

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

Reduce how much old WAL we keep around. (#7098)
Previously we were keeping up to around 6 hours of WAL around by
removing 1/3 every hours. This was excessive, so switch to removing 2/3
which will up to around 3 hours of WAL around.

This will roughly halve the size of the WAL and halve startup time for
those who are I/O bound. This may increase the checkpoint size for
those with certain churn patterns, but by much less than we're saving
from the segments.

Julien Pivotto 8907ba6235 Make TSDB use storage errors
This fixes #6992, which was introduced by #6777. There was an
intermediate component which translated TSDB errors into storage errors,
but that component was deleted and this bug went unnoticed, until we
were watching at the Prombench results. Without this, scrape will fail
instead of dropping samples or using "Add" when the series have been
garbage collected.

Move crucial actions to defer (#6918)
With defer having less of a performance penalty, there is no reason
not to do those crucial operations via defer.

Context: With isolation in place, if we forget to Commit/Rollback, the
low watermark will get stuck forever.

The current code should not have any bugs, but moving to defer helps
to avoid future bugs.

This is also moving the `closeAppend` in the `Commit` implementation
itself to defer. If logging to the WAL fails, we would have missed the
`closeAppend`.

beorn7 f6f4fd6556 tsdb: Do a full rollback upon commit error
I think the previous behavior is problematic as it will leave
`memSeries` around that still have `pendingCommit` set to `true`.

The only case where this can happen in this code path is a failure to
write to the WAL, in which case we are probably in trouble anyway. I
believe, however, we should still try to do the right thing and do the
full rollback. This will implicitly try to write to the WAL again, but
this time without samples, which may even succeed. (But we propagate
the previous error in any case.)

This also adds `a.head.putSeriesBuffer(a.sampleSeries)` to Rollback,
which was previously missing.

This is taken from #6918. Since we probably won't merge #6918 before

(iso.closeAppend is not called if the append fails because of an error

tsdb: don't allow ingesting empty labelsets (#6891)
* tsdb: don't allow ingesting empty labelsets

When we ingest an empty labelset in the head, further blocks can not be
compacted, with the error:

```
level=error ts=2020-02-27T21:26:58.379Z caller=db.go:659 component=tsdb
msg="compaction failed" err="persist head block: write compaction:
add series: out-of-order series added with label set \"{}\" / prev:
\"{}\""
```

We should therefore reject those invalid empty labelsets upfront.

This can be reproduced with the following:

```
cat << END > prometheus.yml
scrape_configs:
  - job_name: 'prometheus'
    scrape_interval: 1s
    basic_auth:
      username: test
      password: test
    metric_relabel_configs:
    - regex: ".*"
      action: labeldrop

    static_configs:
    - targets:

END
./prometheus --storage.tsdb.min-block-duration=1m

Brian Brazil cebe36c7d5 Make head Postings only return series in time range
Series() will fetch all the metadata for a series,
even if it's going to be filtered later due to time ranges.

For 1M series we save ~1.1s if you only needed some of the data, but take an
extra ~.2s if you did want everything.

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.

Stream symbols during compaction. (#6468)
Rather than buffer up symbols in RAM, do it one by one
during compaction. Then use the reader's symbol handling
for symbol lookups during the rest of the index write.

There is some slowdown in compaction, due to having to look through a file
rather than a hash lookup. This is noise to the overall cost of compacting
series with thousands of samples though.
