While doing so, re-introduce the summary/description
annotations. Also, add a few more rules and tweak a few of the
existing ones.

* Add benchmark for sample delivery
* Simplify StoreSeries to have only one loop
* Reduce allocations for pending samples in runShard
* Only allocate one send slice per segment
* Cache a buffer in each shard for snappy to use
* Remove queue manager seriesMtx
It is not possible for any of the places protected by the seriesMtx to
be called concurrently so it is safe to remove. By removing the mutex we
can simplify the Append code to one loop.

Document the behavior of an empty `ec2_sd_config` `region` setting. If this is
omitted or blank, the region is discovered from the instance metadata, if available.
If it is blank and instance region metadata is not available, an error will
result ("EC2 SD configuration requires a region").

This allows other processes to reuse just the remote write code without
having to use the remote read code as well. This will be used to create
a sidecar capable of sending remote write payloads.

It also includes an update of RELEASE.md since this version simplifies a
bit the release process: promu will take care of drafting the GitHub
release.

Lots of alerts are based on ratios (eg. disk usage), and humans are used
to values in percentage in textual descriptions.

The version on goreleaser is broken and different from the one in
Github: golangci/golangci-lint#575 – use the direct Github URL as a
workaround.
Additionally, the installer script attempts to `install -d /go/bin` on
CircleCI, which doesn't work due to permissions. Patch that line out –
we don't need it because we make sure the directory exists anyway.

With the next release of client_golang, Summaries will not have
objectives by default. To not lose the objectives we have right now,
explicitly state the current default objectives.

For my benchmarks on aggregation this reduces allocations by ~5% (~10%
time improvement):
```
benchmark old ns/op new ns/op delta

benchmark old allocs new allocs delta
