* Move remote read handler to remote package.
This follows the pattern I started with the remote write handler. The api/v1 package is getting pretty cluttered. Moving code to other packages helps reduce this size and also makes it reusable - eg Cortex doesn't do streaming remote writes yet, and will very soon.

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.

- 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

* MultiError: Refactored MultiError for more concise and safe usage.
* Less lines
* Goland IDE was marking every usage of old MultiError "potential nil" error
* It was easy to forgot using Err() when error was returned, now it's safely assured on compile time.
NOTE: Potentially I would rename package to merrors. (: In different PR.

Currently there is no way of tracking the value of the
`max_samples_per_send` configuration option, which is commonly tweaked
when integrating with a remote write backend.

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`
Signed-off-by: Bartlomiej Plotka <bwplotka@gmail.com>
* 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.
