Online upgrade using graceful failover/delta recovery/rebalance fails during rebalance of eventing service

Steps to Repro
1. Create a 3 node 6.5.2-6634 cluster(172.23.107.222,172.23.107.223,172.23.107.217)
2. do a swap rebalance of 6.6.6-10576 node(172.23.107.99) with 6.5.2-6634(172.23.107.223) node. This succeeds.
3. Graceful failover a 6.5.2-6634(172.23.107.217) node. Upgrade the build to 6.6.6-10576. Do a delta recovery and click on rebalance. This rebalance fails continuously on retry as shown below.
