Finer controls for Logging to determine what goes to stdout, to OSW or to both. Avoid capturing stdout twice

[jmarrec]

Enhancement Request

• Determine what goes to stdout, to out OSW, or to both
• Avoid having the same information going in the OSW as a log + as stdout / stderr key

Detailed Description

We capture stdout/stderr in the OSRunner and setStdOut/setStdErr on the WorkflowStepResult, which in turns is written to the final out OSW. We often end up seeing the same warnings/errors in the stdout key and in the step_warnings, step_errors, etc.
