Analysing the latest release

The script is scripts/analyse_latest_release.rb.

The script can be run from a console, or by invoking the workflow "Store latest release metadata" from this repository.

The script uses the SHA of the latest release and the built_at time, as reported by a health check endpoint, and the previous recorded SHA (if available in Influx) to analyse the release.

It relies on the specific structure of the data returned by the health check endpoint, and it needs a previous release to have been stored in the data bucket to have something to compare against.
