Env:
3 controller setup
new installation, OSA tag 17.0.6, centos 7.5 1805

Neutron with HA router VRRP setup.

Neutron-l3-agent fails with the following stacktrace: http://paste.openstack.org/show/MTMvb6BMWw9Aa6YTI0vX/

on controller 1, neutron-keepalived-state-change is not present in the current netns $PATH:

fixing the script by symlinking
`ln -s /openstack/venvs/neutron-17.0.6/bin/neutron-keepalived-state-change /usr/local/bin/neutron-keepalived-state-change` leads to http://paste.openstack.org/show/726129/ (where the HA IP is present on two controller nodes, i expected only one)
