* store+compactor: pre-compute index cache during compaction (thanos-io#986)

Fixes first part of thanos-io#942

This changes allow to safe some startup & sync time in store gateway as it is no longer is needed to compute index-cache from block index on its own. For compatibility store GW still can do it, but it first checks bucket if there is index-cached uploaded already.

In the same time, compactor precomputes the index cache file on every compaction. To allow quicker addition of index cache files we added `--index.generate-missing-cache-file` flag, that if enabled precompute missing files on compactor startup. Note that it will take time and it's only one-off step per bucket.

* bucket verify: repair out of order labels

* verify repair: correctly order series in the index on rewrite

When we have label sets that are not in the correct order, fixing that
changes the order of the series in the index.  So the index must be
rewritten in that new order.  This makes this repair tool take up a
bunch more memory, but produces blocks that verify correctly.

* Fix the TSDB block safe-delete function

The directory name must be the block ID name exactly to verify.  A temp
directory or random name will not work here.

* verify repair: fix duplicate chunk detection

Pointer/reference logic error was eliminating all chunks for a series in
a given TSDB block that wasn't the first chunk.  Chunks are now
referenced correctly via pointers.

* PR feedback: use errors.Errorf() instead of fmt.Errorf()

* Use errors.New()

Some linters catch errors.Errorf() as its not really part of the errors
package.

* Liberally comment this for loop

We're comparing items by pointers, using Go's range variables is
misleading here and we need not fall into the same trap.

Root cause:
* runutil defered capture error function was not passing error properly so unit tests were passing, event though there was bug
* streamed block write index cache requires index file which was not closed (saved) properly yet. Closers need to be closed to perform this.

* add compare flags func to compare flags between prometheus and sidecar (thanos-io#838)

Original message:

* update documentation for a max/min block duration

add compare flags func to compare flags between prom and sidecar

* fix some nits


Functional change: now we check the configured flags (if possible) and error out if MinTime != MaxTime. We need to check this always since if that is not true then we will get overlapping blocks. Additionally, an error message is printed out if it is not equal to 2h (the recommended value).

* store/proxy: properly check if context has ended (thanos-io#1082)

How the code was before it could happen that we might receive some
series from the stream however by the time we'd send them back to the
reader, it would not read it anymore since the deadline would have been
exceeded.

Properly use a `select` here to get out of the goroutine if the deadline
has been exceeded.

Might potentially fix a problem where we see one goroutine hanging
constantly (and thus blocking from work being done):

```
goroutine profile: total 126

 ## Unreleased
 
-### Added
-- [#811](https://github.com/improbable-eng/thanos/pull/811) Remote write receiver
-- [#798](https://github.com/improbable-eng/thanos/pull/798) Ability to limit the maximum concurrent about of Series() calls in Thanos Store and the maximum amount of samples.
+## [v0.4.0](https://github.com/improbable-eng/thanos/releases/tag/v0.4.0) - 2019.05.3
 
-New options:
+:warning: **IMPORTANT** :warning: This is the last release that supports gossip. From Thanos v0.5.0, gossip will be completely removed.
 
-* `--store.grpc.series-sample-limit` limits the amount of samples that might be retrieved on a single Series() call. By default it is 0. Consider enabling it by setting it to more than 0 if you are running on limited resources.
-* `--store.grpc.series-max-concurrency` limits the number of concurrent Series() calls in Thanos Store. By default it is 20. Considering making it lower or bigger depending on the scale of your deployment.
+This release also disables gossip mode by default for all components.
+See [this](docs/proposals/approved/201809_gossip-removal.md) for more details.
 
-New metrics:
-* `thanos_bucket_store_queries_dropped_total` shows how many queries were dropped due to the samples limit;
-* `thanos_bucket_store_queries_concurrent_max` is a constant metric which shows how many Series() calls can concurrently be executed by Thanos Store;
-* `thanos_bucket_store_queries_in_flight` shows how many queries are currently "in flight" i.e. they are being executed;
-* `thanos_bucket_store_gate_duration_seconds` shows how many seconds it took for queries to pass through the gate in both cases - when that fails and when it does not.
+### Added
 
-New tracing span:
-* `store_query_gate_ismyturn` shows how long it took for a query to pass (or not) through the gate.
