Remake CD build summary output.

[u-ways]

The current build summary for each environment image run is clattered and has lots of unnecessary duplication (i.e. the "What are you looking at?" section can just be part of the README.md and you can redirect people there...)

Remake the generated properties file values display as an easy to read/view/compare markdown table while guiding users to where they can download each environment artifacts (i.e. links for downloads of application.properties an generated image...)

Please use a builder pattern for generating the markdown table in the propactive-demo project...
