I think this should be in the 'new features' section, considering that it's an 
option with its own flag.

Good point.  I'll add some notes on that and squash this update with the update 
on non-possible rolling upgrade from 1.6 to 1.7 due to the update of the 
replica management scheme.

Is the concept of 3-2-3 and 3-4-3 completely new to users? I know it's been the 
shorthand terminology of the feature for a while. But it might be worth 
defining what it is. Something like: "Kudu now adds a replica before removing a 
bad replica instead of aggressively removing replicas  before a replacement is 
ready." Or perhaps calling it "replace first" vs "evict first" since I think 
replication factors other than 3 can be used.

What happens if the replication factor is 5? Does it still replace first?
