python-pbr package not installed on config nodes

R1.10 34

In Icehouse distribution on CentOS, on config nodes python-pbr package is not installed.
This is resulting neutronclient shell commands to fail.

Workaround is to install the package manually from /opt/contrail/contrail_install_repo/python-pbr-0.8.0-1.el6.noarch.rpm
i.e.
yum install /opt/contrail/contrail_install_repo/python-pbr-0.8.0-1.el6.noarch.rpm

[root@nodec20 ~]# source /etc/contrail/openstackrc
[root@nodec20 ~]# neutron net-list
