If dpu throws DPUConfigException then it's logged
If existing pipeline is open for edit then pipeline detail is hidden automatically
Execution speed up (wait time removed) - removed @Asynch from SqlAppenderImpl.flush as we need to wait at the end of the method from pipeline.Executor
DPU generated description is used if dpu's description in left blank in DPU "Templates" and "import"
