Abridged logging of the Echo/Echo Warning/Echo Error commands

Supply Optimization (Planning Engine) no longer log Echo/Echo Warning/Echo Error commands and the completion status when the commands complete as intended. For example , before this release, the job log for 'Echo Warning: "ABC"ABC";' command looked like as follows:

Started executing workflow "temp".
Command: "Echo Warning: "ABC"".
    ABC
Command "Echo Warning" completed with warnings.
Workflow "temp" completed with warnings (duration 00:00:00).

With this release, the job log for the same command is as follows:

Started executing workflow "temp".
ABC
Workflow "temp" completed with warnings (duration 00:00:00).
