+... This suite uses exabgp. It is configured to have 3 peers (all 3 nodes of odl).
+... Bgp implemented with singleton accepts only one incomming conection. Exabgp
+... logs will show that one peer will be connected and two will fail.
+... After killing karaf which owned connection new owner should be elected and
+... this new owner should accept incomming bgp connection.
