Define outputs

[jasonjoo2010]

In current design the standard output/error stream is taken as the main outputs of a job. But it can be totally messes. And the exit code dis also included in it with a header of [exitcode]. Things are even worse when you have some outputs unmuted like curl. These kind of commands will output a lot of segments of format characters to form a better looking in terminals.

So it's necessary to define a new stream or format in current streams which is the output of job, maybe a one line string in JSON, eg. .
