Silence pip unless there is an error
As per the 2018-01-14 demo, this was a feedback:
Pip version 10.0.1 red warning. Micael: Should we silence pip? Micael: We can either upgrade pip (I don’t like that) or silence the ouput unless there is an error (I like that)
I think we should simple silence pip unless there is a problem.
Make the error YELLOW and not RED when it's a warning.
