adding the beginnings of the release doc with steps, fixing a bug in the release_prepare.sh script and tweaking the output based on the current process.

* improvements in bigtable backup tool

Added some metrics for monitoring of backup jobs
Added a command to delete out of range backups, otherwise, there would be more backups than expected and alerts would start firing for unexpected backups

* chore(packaging): set tag length to 7

relied on git approximation before, which causes problems with other parts of
the automation.

Because we do not need the tag to be strictly unique, but just to identify the
latest version, limiting to 7 is fine.

If this ever causes problems, raise the limit but make sure to update all other
places as well.

* chore(packaging): request at least 7 characters

Because drone.io provides us with native ARM runners, we evaluate the platform to figure out if it is a suitable replacement for CircleCI and qemu.

Configuration is done using .drone/drone.jsonnet, the .drone/drone.yml is generated from that.
Images are built on amd64, arm64 and arm, natively and without emulation. This allows to get rid of cross-compilation, which in turn allows more advanced builds (CGO, etc.)

Hopefully this will make the CI faster and more reliable in the future. Let's see!

This PR sets up an automated release pipeline to cross compile build artifacts and publish them to github. mitchellh/gox is used for building, ghr for publishing

* Tool for creating and managing periodic tables stored in Bigtable

It has 2 commands:
1. backup-active-periodic-table: For backing up active periodic table
2. ensure-backups: It helps ensure right tables are backed up and retain only single backup for non active periodic tables

- bump build image to 0.4.0
- re-gen protos
- re-add deploy task

This finally adds support for multiple architectures!  

Images are now built using BuildKit (actually img), Dockerfiles were parameterized to allow this.
Containers are still built on alpine, using QEMU and binfmt as a kernel compatibility layer to allow RUN steps in these.

CircleCI has been fully revamped, to speed up builds and de-duplicate the configuration.
Makefile has been extended with additional logic to shadow the multi-arch to non-CI users.

Happy hacking on Raspberry Pi and friends :)

* Add a scrape config for pods without name or app labels.

Signed-off-by: Tom Wilkie <tom.wilkie@gmail.com>

* rebase with master and update to prefer name label but fallback to controller name

* Update scrape_config to use pod controller_name in the job

If a pod has a "name" label we use that in the job name. Otherwise,
- If the pod was created directly by a controller (statefulset,
  daemonset, job) then we use that controller_name.
- if the pod was created by controller created by a controller
  (deployment, cronJob) then we use the parent controller name.

- add a scrape_config.sh tool that generates the scrap_configs
  for promtail.sh and helm chart from the ksonnet lib.

* Reduce duplication in jsonnet.

issue #313

kubelet creates a new log file when a container is restarted.
So we need to catpure all log files in the
`/var/logs/pods/<uid>/<container_name>/` dir.

__path__ is now expected to be a `glob` match, not a directory.  In k8s the "glob" expression needed is just the exact file path of the container log, which is `/var/log/pods/<podUID>/<container_name>/0.log`

fixes #190
Pods can have multiple containers. This fix ensures that we collect
logs for all containers.
