websocket.WebSocketBadStatusException from websocket_client 33, some platforms onyl support 32

[Josh Hershberg]

Description of problem:

Setup: ODL HA Clustered Setup
3 Controllers running neutron servers + ODL Controller.
3 Compute nodes.

In OSP12 ODL Clustered setup, we noticed the following exception in neutron server logs.

IMO, there are two ways to fix the issue. Either we bump the python-websocket-client package on RHEL7.4 or avoid using the WebSocketBadStatusException status in networking-odl.

Version-Release number of selected component (if applicable):
The following packages were used when the issue was reproduced.
python-websocket-client-0.32.0-116.el7.noarch
python-neutron-11.0.0-0.20170807223712.el7ost.noarch
python-networking-odl-11.0.0-0.20170806093629.2e78dca.el7ost.noarch
