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

I am looking of a reviewer ([~brandon.williams]  [~jmckenzie] )

[https://github.com/apache/cassandra/pull/1900]

Logs are written via appenders before virtual tables are registered so that 
means that we would not capture all the logs in vtables after a node is 
started. I have covered this case as well, it will be visible in the PR.

Also, it is not desirable to have multiple appenders of same class here as we 
would have entries in vtable multiple times (from each appender). Hence, on 
startup, I am checking that there is one vtable appender present at most and I 
fail the start if there are many.

It is all tested as well.

> The warnings and errors are currently only accessible through Cassandra logs. 
> Automating the monitoring of the nodes would be much easier/secure if we can 
> make use of virtual tables to get the logs.
