Parameters Versioning

[ismailsunni]

Since we want to keep both parameter with Python 2 (for realtime in meantime) and Python 3 (migration purpose to QGIS 3), we need to have proper versioning in this parameter repository.

I think we should go with version 2.0 for the QGIS 3 version.

I think we can close this.
