Subject: [PATCH] target: add option to invoke to redirect stderr
The stderr of a command is not propagated as part of the command
output. However, some workloads/commands write vital output to
stderr. For this reason, we add an option to invoke which redirects
stderr to stdout (redirect_stderr). This is disabled by default.
