Counter steer against too noisy logs

[hiddenalpha]

In one downstream project we need more error details (like stacktraces) for bug hunting. But in another downstream project, this causes performance issues due to too much stack traces. This change provides the base to fulfill both projects needs.

Changes all look good. Before merging this to develop I would suggest to replace all occurrences of logging new Exception(...) with the new factory method
