Summary     : Python API and CLI for OpenStack Glance
Description :
This is a client for the OpenStack Glance API. There's a Python API (the
glanceclient module), and a command-line script (glance). Each implements
100% of the OpenStack Glance API.

How reproducible:
100%

Steps to Reproduce:
1. update to python-glanceclient-0.17.3-1.el7ost
2. all deprecated CLIs (glance, nova, neutron) work but openstack doesn't anymore
3. 

Actual results:
[root@osp2 ~(keystone_admin)]# openstack image list
ERROR: openstackclient.shell Exception raised: (python-glanceclient 0.17.3 (/usr/lib/python2.7/site-packages), Requirement.parse('python-glanceclient>=0.18.0'))


Expected results:
'openstack' should work fine and not bear references to glanceclient-0.18.0
