Description

In our production env, when we expand an existing cluster to a new DC, we are doing following steps:
1. set replication factor to be 0 for the new DC.
2. bootstrap all nodes in the new DC.
3. set the replication factor to be 1 and start the rebuild.

I find the NoReplicationTokenAllocator does not work with replication factor 0, and this patch will fix it.
