2020.09.17: Merge pull request #240 from goern/release-20200916

Release 2020.09.17

First of all, why do we use CalVer for the core repository? Because the Thoth Services and
Tools consist of a large set of GitHub-hosted repositories,
Python modules, container images and
even RPMs.
Any of these components might yield to a release at any time. This release note file covers the aggregation of important
releases in the contexts of

• Thoth Service - our back end services, the knowledge generation
• the toolbox - command line tools and their packages

Index of Justifications

Starting with this release, we publish a human-readable list of justifications. This list is referenced from any thamos advise output on the terminal, or any pipeline integration. Its purpose is
to show the knowledge contained in Thoth's services and to act as a jump-page to more detailed and background information.
Especially the jump-page character is important to users, as we don't want to clutter the terminal/pipeline output, but
want to reveal to results of our reinforcement learning process in a transparent way.

Breaking Changes

None are known, please file issues if you hit any!

Adviser

Adviser is Thoth's recommendation engine and software stack generator.

• a review of CPU types, and the way we create recommendation for AVX2 and Tensorflow has been done
• some new TensorFlow related observations/justfications have been created
• a recommendation to configure MKL correctly was added
• general stabilization of Argo-Workflows based backend services
• adviser now supports advises specific for manifest changes (e.g. adjusting environment variables of OpenShift
  DeploymentConfigs)
