Generate the process picture (SVG) at build time

Currently the developer has to generate manually the process SVG following the complex procedure described here:

http://docs.jboss.org/kogito/release/1.6.0/html_single/index.html#con-bpmn-process-svg-addon_kogito-developing-process-services

The process is really error prone:

• name it and place in the correct location
• keep in sync with the BPMN file

It would make much more sense to generate the picture automatically at build time.

Goal: improved the developer experience!
