Task #6559 This is the third iteration. Introducing loops and additional recipes for executables in general. Both not 100% finisehd. Loops work but more work has to be done concerning in/output of the steps within the loop. Loops are pipeline steps themself which hold a list of steps they add to the pipeline run. If not using a fixed number of iterations one step in the loop should be a break condition step. This step specifies in its output if the loop should break and the pipeline continue its work. The parsetonly recipe now handles dppp and awimager steps. For patching the parset on node level in/output keywords have to given in the step control section.
