@HeartSaVioR added resolution details in the description of the PR. Adding
one more point here: `(kill-existing-workers-with-change-in-components
supervisor existing-assignment new-assignment)` is not needed in
`sync-supervisor` as it kills all the workers with invalid state which includes
the old workers and rebalanced workers.
