* do not swallow exception triggered inside SWA handling
--> write it to the log
The real change is in src/com/sap/piper/Utils.groovy
All the changes in the tests are dealing with mocking the echo method
used in the Utils class mentioned above.
On groovy level we take into account:
- parameters via signature
- project config
- landscape config(s)
- for docker: nested and plain config
also more tests added ...
