user is unable to add the node back to the cluster because the failed over node is stuck in warmup phase

Have not seen this issue previously ever on 181. Seems to be something new.

Test case that failed
swaprebalance.SwapRebalanceFailedTests.test_add_back_failed_node,replica=3,num-buckets=5,num-swap=2,swap-orchestrator=True,keys-count=800000

1) Failover 2 nodes, including the orchestrator
2) Rebalance them out
3) Add them back and rebalance in, without cleaning them.
