Zero flows populated in all switches when connected to Leader Node.

Zero flows populated in switches when connected to Leader Node.

Flows : 10k flows/switch
Switches : 15

Steps to Reproduce :
====================
1. Get Inventory Follower and Leader information

2. Start Mininet Connect To Follower Node1

3. Add Bulk Flow from follower node1

4. Get Bulk Flows and Verify In Cluster config DS and verify all flows are installed

5. Verify Default flows in switches when connected to Follower node. Here it shows zero flows in all 15 switches

6. Verify Flows In Switch when connected to Follower Node .

7. Flows will get installed when connected to Follower node.

8. Stop and start mininet to Leader Node.

9. Verify Flows in switch when connected to Leader Node .

10. Issue is consistent . Zero flows will be installed in all 15 switches when connected to Leader Node.

When connected to Follower node1 , populated total flows in all switches (150000.0)
After stop and start mininet when connected to Follower Node , populated total flows in all switches (150000.0)
Stop and start mininet connect to Leader node

sudo mn --controller 'remote,ip=10.29.12.
213,port=6633' --topo linear,15 --switch ovsk,protocols=OpenFlow13

Zero flows populated when connected to Leader Node.(0.0 != 150000.0)
