Stream log output of terminals to `gp rebuild`

[loujaybee]

When running gp rebuild I found myself not wanting to have to open up the debug workspace every time to see the log output. I found myself wanting to see the logs inline with the main gp rebuild logs, e.g. with some command like: gp rebuild --logs that would stream them to the main workspace rather than having to open the debug workspace each time.

It maybe good to do it by default. My only worry will be that prompt with how to open in another window would be lost.
About --logs not sure, since we have --log=info already. Wonder what could be an alternative option name that it is more specific about tasks?
