Move remote read handler to remote package. (#8536)
* 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.

Combine Appender.Add and AddFast into a single Append method. (#8489)
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.

Tom Wilkie d479151f1f Various enhancements and refactorings for remote write receiver:
- 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

Fix panic when updating a remote write queue (#7452)
Right now Queue Manager metrics are registered when the metrics struct
is created, which happens before a changed queue is shutdown and the old
metrics are unregistered. In the case of named queues or updates to
external labels the apply config will panic due to duplicate metrics.

Instead, register the metrics as part of starting the queue as we always
guarantee that Stop will be called before a new Start.

Pending Samples metric includes samples in channel (#7335)
* Pending Samples metric includes samples in channel

The pending samples metric should also include samples waiting in the
channels to be sent to provide a more accurate measure. In addition,
make sure that the pending samples is reset to 0 anytime a queue is
started as we remake all of the shards at that time.

storage: Adjusted fully storage layer support for chunk iterators: Remote read client, readyStorage, fanout. (#7059)
* Fixed nits introduced by https://github.com/prometheus/prometheus/pull/7334
* Added ChunkQueryable implementation to fanout and readyStorage.
* Added more comments.
* Changed NewVerticalChunkSeriesMerger to CompactingChunkSeriesMerger, removed tiny interface by reusing VerticalSeriesMergeFunc for overlapping algorithm for
both chunks and series, for both querying and compacting (!) + made sure duplicates are merged.
* Added ErrChunkSeriesSet
* Added Samples interface for seamless []promb.Sample to []tsdbutil.Sample conversion.
* Deprecating non chunks serieset based StreamChunkedReadResponses, added chunk one.
* Improved tests.
* Split remote client into Write (old storage) and read.
* Queryable client is now SampleAndChunkQueryable. Since we cannot use nice QueryableFunc I moved
all config based options to sampleAndChunkQueryableClient to aboid boilerplate.

In next commit: Changes for TSDB.

* Refactored and simplified fanout with improvements from incoming chunk iterator PRs.

* Secondary logic is hidden, instead of weird failed series set logic we had.
* Fanout is well commented
* Fanout closing record all errors
* MergeQuerier improved API (clearer)
* deferredGenericMergeSeriesSet is not needed as we return no samples anyway for failed series sets (next = false).

* Used sync.Once in secondary Querier to achieve all-or-nothing partial response logic.
* Select after first Next is done will panic.

NOTE: in lazySeriesSet in theory we could just panic, I think however we can
totally just return error, it will panic in expand anyway.

Buckets are now: {0.03125, 0.0625, 0.125, 0.25, 0.5, 1, 2, 4, 8, 16, 32, 64, 128, 256, 512}
