rebased on top of #8007.

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.

Right now a new segment might be created unnecessarily if the
uncompressed record would not fit, but after compression (typically
reducing record size in half) it would.

* CleanupTombstones refactored, now reloading blocks after every compaction.
The goal is to remove deletable blocks after every compaction and, thus, decrease disk space used when cleaning tombstones.

In the previous version, 1.18.0, the "megacheck" linter paid attention
to the '//lint:ignore' comment, but that is no longer there.
Newer version pay attention to '//nolint:<linter>,<linter>,...'
comments, optionally followed by a "second" comment introduced by '//'.
Update the directives to use this style.

We're seeing compactions that are taking hours in Cortex which this is
missing. I know while it is not common in Prometheus, I am pretty sure
there are setups where compaction takes longer than 512s. On our own
Prometheus the average compaction duration is 566s.

As we're looking to expand what's in the WAL,
having old Prometheus servers ignore the new record types
rather than treating them as corruption allows for better
upgrade/downgrade paths.
Adjust some tests accordingly, so they're still testing what they're
meant to test.

I did not want to move those in previous PR to make it easier to review. Now small cleanup time for readability. (:
## Changes
* Merge series goes to `storage/merge.go` leaving `fanout.go` for just fanout code.
* Moved `fanout test` code from weird separate package to storage.
* Unskiped one test: TestFanout_SelectSorted/chunk_querier
* Moved block series set codes responsible for querying blocks to `querier.go` from `compact.go`

* tsdb: Added ChunkQueryable implementations to db; unified compactor, querier and fanout block iterating.

* 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.
