Stream info printed in DEBUG mode

[artsyjian]

DEBUG=1 causes low level stream info to be printed, which is makes it hard to debug.

I prefer DEBUG=1 to print only Hokusai specific debug information.

ip-10-0-0-17:hokusai-sandbox jxu$ DEBUG=1 hokusai staging run --tty sh                                                If you don't see a command prompt, try pressing enter.
