* Optimise deploy artifacts step
authelia-scripts is not required to publish GitHub artifacts as we utilise [Hub](https://hub.github.com/), this should save ~10 seconds in this step.
* Specify release number in pipeline
* Change buildkite and github published artifacts back to gzip
* Update README.md
* Build docker image upfront in CI and use it in integration tests.
Previously, the development workflow was broken because the container
generated from Dockerfile.CI was used in dev environments but the binary
was not pre-built as it is on buildkite. I propose to just remove that
image and use the "to be published" image instead in integration tests.
This will have several advantages:
- Fix the dev workflow.
- Remove CI arch from authelia-scripts build command
- Optimize CI time in buildkite since we'll cache a way small artifact
- We don't build authelia more than once for earch arch.
* Fix suites and only build ARM images on master or tagged commits
* Optimise pipeline dependencies and Kubernetes suite to utilise cache
* Run unit tests and docker image build in parallel.
* Fix suite trying to write on read only fs.
