Detect all usages of @ConfigProperty

[Riduidel]

In order to have a good documentation, it would be cool to have all injected config properties listed somewhere (in the README, ideally).

This would require

• Scanning the source code for all @ConfigProperty usages
• List thoses in a markdown file with the associated comment (and also the class/line where it was found)
• Publish that markdown file in git

A (quite complex) bonus would be to also extract the API calls (like in ExportToCSV.CSVTableExport#configureTableExportFor)
