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.

In running Prometheus instances, compressing the records was shown to
reduce disk usage by half while incurring a negligible CPU cost.

In cases where a rename fails the fileutil.Replace would delete the
source files/folder.
There is no easy way to make directory renaming atomic, but for files
os.Rename is atomic and replaced the destination file so there is no
need to remove the destination file explicitly.

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

With the next release of client_golang, Summaries will not have
objectives by default.
As it turns out, for prometheus_tsdb_head_gc_duration_seconds and
prometheus_tsdb_wal_truncate_duration_seconds, the objective-less
default makes more sense then the current default.
To make sure we do the right thing before and after the upcoming
release of client_golang, I have set the objectives explicitly
wherever that was not the case so far:
- prometheus_tsdb_head_gc_duration_seconds and
prometheus_tsdb_wal_truncate_duration_seconds now have no objectives
explicitly.
- prometheus_tsdb_wal_fsync_duration_seconds now explicitly uses the
previous default objectives.

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.
