Implement templates for Extraction Modules

[anna-g-arbeiter]

Extraction Module configuration Templates could be developed similar to the Profile Templates to export and ship single configured modules.

Profile Templates save a list of JSON configuration files. Each one of these files represent a configured Extraction Module. A Template of an Extraction Modules would be just one of these JSON files, without all the surrounding Profile stuff.

Furthermore an import/export functionality is needed to import these Extraction Module Templates into existing Profiles.
