Merge Wendelin Telecom business templates

Merge all Wendelin Telecom business templates into mainline Wendelin as per JP's request, making Wendelin Telecom generic.

Wendelin Telecom is a Wendelin configuration dedicated to the automatic ingestion and processing of ORS enb.xlog log contents into KPIs for viewing by clients.

I have left the individual bt5 commits for easier legibility for now; we can discuss how to organize the commits before merging.
