---------------------------------------------
LGTM
> NoReplicationTokenAllocator should work with zero replication factor as well.

> Project: Cassandra
> Issue Type: Improvement
> Reporter: Dikang Gu

> Fix For: 3.12

>
> 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.
