Added contrail ifmap-server management code

Added contrail ifmap-server management code.

ifmap-server and other contrail services  need below services
up and running

1. cassandra
2. zookeeper
3. redis
4. haproxy-contrail
5. rabbitmq
Current contrail implementation always use its own IP address, so it is. I am following current contrail implementation first, make sure everything is working and then we can make changes. 

Moreover I dont have any IP available in the module (except localhost) and cannot assume any specific ethernet (eth0/eth1 etc) to be present in the system.

Is there a reason you think, there could be a problem on defaults to be first interface?
