> After STORM-1976, Nimbus doesn't clean up corrupted topologies.
> (corrupted topology means the topology whose codes are not available on blobstore.)
> Also after STORM-1977, no Nimbus is gaining leadership if one or more topologies are corrupted, which means all nimbuses will be no-op.
> So we should provide a tool to kill specific topology without accessing leader nimbus (because there's no leader nimbus at that time). The tool should also determine which topologies are corrupted, and show its list or clean up automatically.
