Comment 2 for bug 1649467

Enabling ssl @ rabbitmq server is the root cause of this issue.
Presently, contrail-alarm-gen doesn’t support rabbit_use_ssl option.
Therefore, connection to rabbitmq is stuck and alarm-gen doesn’t register with discovery service.

adding rabbit_use_ssl option in contrail-alarm-gen should be the solution to this.
Also, VncKombuClient should not be stuck if the connection to rabbitmq fails.
