Change subject: KUDU-3304: [Alter] Support to alter table's replication factor
......................................................................


Patch Set 12:

Thinking more on my previous comment, even if majority of the replicas are not 
down, lets say 1 out of three replicas is down, if we reduce the replication 
factor to 1, based on the below it appears it might choose the unhealthy 
replicas to evict, but a test case to be sure wouldn't hurt to ensure the 
healthy replicas are not evicted. 
https://github.com/apache/kudu/blob/master/src/kudu/master/catalog_manager.cc#L4873

OR
Do we want to not change the replication factor if even one of the replicas is 
not running to be on a safe side. Probably Alexey/Andrew/Bankim can add their 
opinions
