Allow only showing stdout or stderr when using --success-output and --failure-output #1688
Description
I'm writing a file parser and when I get a new version of the format I like to add the samples to my tests.
However, this means that the tests will start hitting todo!() and panic!() and this pollutes the output of the tests:

In these cases stdout has no useful additional information compared to stderr, so I would like to disable it.
I was thinking of the following:
--failure-output immediate-> outputs both stdout and stderr (current case)--failure-output stdout=never-> does not output to stdout, uses default for stderr--failure-output stdout=never,stderr=immediate-> does not output to stdout, immediate output for stderr
Another option is adding more flags.
