---------------------------------------

Thanks Dinesh. Applied the most of the changes you suggested. 

> Add CAS “uncertainty” and “contention" messages that are currently propagated 
> as a WriteTimeoutException.

> Right now, CAS uncertainty introduced in 
> https://issues.apache.org/jira/browse/CASSANDRA-6013 is propagating as 
> WriteTimeout. One of this conditions it manifests is when there’s at least 
> one acceptor that has accepted the value, which means that this value _may_ 
> still get accepted during the later round, despite the proposer failure. 
> Similar problem happens with CAS contention, which is also indistinguishable 
> from the “regular” timeout, even though it is visible in metrics correctly.
