Dragon Launcher Prototype

[al-rigazzi]

This is the first prototype of the new Dragon-based launcher.

Issues to fix (or to defer to a future PR):

• [x] Several telemetry test errors
• [ ] Missing batch settings for Dragon launcher
• [x] Use Process Groups for MPI-based applications - we have process groups but Dragon team is working on a more complete API
