[Clustering]: Switch state resync is not happening after controller restart [Routed RPC issue]

Build used :
===================
Karaf distro from latest ODL Beryllium master code

Test Type :
===================
switch state resync after cluster node restart.

Objective of test :
===================
verify switch resync when node is restarted.

Test Steps :
============
1. Bring up healthy 3 node cluster say c1, c2 and c3. c1 is leader.
2. connect OVS switch to c3 node. c3 node is entity owner as shown in attached snapshot.
3. push 10 flows using flow-config-blaster script from follower c3
4. total flows in switch, config DS and operational DS is 10
5. restart c3 node
6. connect OVS switch to c3 node, c3 node is entity owner as shown in attached snapshot.
7. switch is showing 2 flows
8. config DS is showing 10 flows and Operational DS is showing 2 flows

Note: Output shown for Flows in switch and Operational DS in Step 7 and Step 8 are not consistent. In 4 times, i have seen output as 4, 0, 10 and 2 flows.

Controllers (to cross-check logs):
===================================
c1 - Controller 1 with IP 10.183.181.41 - config-inventory-shard leader
c2 - Controller 2 with IP 10.183.181.42 - config-inventory-shard follower
c3 - Controller 3 with IP 10.183.181.43 - config-inventory-shard follower

Enclosed Logs:
==============
c1.karaf.log for controller c1
c2.karaf.log for controller c2
c3.karaf.log for controller c3
snapshot for entity ower from c3
snapshot for flows in OVS switch
