add AWI webODV

Added a new service (AWI webODV).

1. 665249e8: Add submodule git submodule add ../awi-webodv.git subprojects/AWI-WebODV
2. f366363e: Metadata such as Onboarding time, display name; and internal softlinks
3. 97d8d6ce: Time is given in non-standard format, so a specific descriptor is defined here
4. 7e3677cc: Add the (yet very trivial) plots to gallery (optional)
5. 75f942f0: Placeholder for KPI weights. So far all set to zero, to be adapted later by Cloud Management.

To do:

• Approval of from Service Integration that service data is ready and this can be merged to master @agiesler
• Definition of appropriate weights from Cloud Management @SpickerHZB 👉 later, after onboarding
