Netvirt fails to add all the ODL nodes as controllers to br-int

Image Tested: https://nexus.opendaylight.org/content/repositories/autorelease-1484/org/opendaylight/integration/distribution-karaf/0.5.0-Boron/distribution-karaf-0.5.0-Boron.zip

Step 1: Setup 3node ODL

Step 2: Stack three openstack nodes

Step 3: In one of the nodes, the sudo 0vs-vsctl show displayed br-int with only one ODL added as controller.

this observation is a bug because if that ODL goes down the instances in that compute node will not be able to work well

Please note: Actually a failover was done in ODL1 for some testing. so the entity owners were collected after failover so they do not reflect the situation before failover i.e. when the problem occurred. But the karaf logs should be helpful.

When ODL Managers are set in local.conf ODL_OVS_MANAGERS=10.128.0.9,10.128.0.5,10.128.0.6

the expectation is any br-int created by NEtvirt will set all these ODL nodes as openflow controllers.

Among the 3 Openstack nodes, the br-int in one of the nodes had only 10.128.0.9 as openflow controller.
