The createIndexes command is not resilient to errors like HostUnreachable and InterruptedDueToReplStateChange. Presently, the create_index_background_unique.js and create_index_background_unique_capped.js workloads fail frequently in suites like concurrency_sharded_multi_stmt_txn_kill_primary because these suites prompt these sorts of errors and rely on lower-level retry logic to handle them.

These workloads should be blacklisted from concurrency_sharded_multi_stmt_txn_kill_primary, concurrency_sharded_multi_stmt_txn_terminate_primary, and concurrency_sharded_multi_stmt_txn_with_stepdowns.
