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