kie-issues#1036: Adapt kie-tools Jenkins jobs to build and publish packages/kogito-swf-{devmode,builder}

[rodrigonull]

Closes: apache/incubator-kie-issues#1036

In this PR:

• Update daily-dev, staging and release jobs to publish kogito-swf-builder and kogito-swf-devmode images to quay.io
• Update Kie tools CI base image to add python tooling
• Refactor stage Jenkins job to avoid errors due to the size of the pipeline

@rodrigonull Slight change of plans regarding the daily-dev and staging jobs. We're gonna publish everything to quay.io/kiegroup, always. On daily-dev, the tag for the kogito-swf-{devmode,builder} images should be latest, mimicking what was being done on incubator-kie-kogito-images.

For staging, we can use the x.y.z-prerelease tag like we do for other images as well. Still publishing to kiegroup.

This was necessary because of the way kogito-serverless-operator points to these images. It is not prepared to use a different organization name on its bump-version.sh script.

We'll need to make sure that the new kogito-serverless-operator package is well configured for these assumptions, but don't worry about that, we can change it on

• Adapt packages/kn-plugin-workflow on kie-tools to point to packages/sonataflow-images and packages/sonataflow-operator incubator-kie-issues#1035

Oh, and btw, for the daily-dev script, we need the -nightly prefix on them too.
