Open Stack

Hi,
I currently have a patch up for review (https://review.openstack.org/#/c/81373/) to limit psutil be <2.0.0.
2.0.0 just came out a couple weeks ago, and breaks the API in a major way.  Until we can port our code to the
latest version, I suggest we limit the version of psutil to 1.x (currently there's a lower bound in the 1.x
range, just not an upper bound).

Best Regards,
Solly Ross
