LiveReaders are instantiated `number of remote write queues * segments`
times, which would cause double registration of the metrics. Instead
this should be orchestrated by the layer above, instantiating the live
reader.

Previously, the wording could be misunderstood as setting honor_labels
to "false" for federation.
This also adds scraping the Pushgateway as a typical use case for
honor_labels=true.

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.

* refactor block size calculation
The block size is kept in memory and not in the meta file anymore.
It now includes the size of the meta file itself for a more
correct block size.
It fixes a bug where the size didn't change when calling `block.Delete()`.
Adds a dedicated test to ensure correct block sizes.
This allows opening a db in a read only mode as it doesn't write to the meta file anymore.

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.
