STORM-405: Add kafka trident state so messages ca be sent to kafka topic...

...s
do we really need to be able to handle multiple topics here? if we have 2 topics and we can successfully send the message to the first one but fail to send it to the second one we'd throw a FailedException resulting in inconsistencies between the topics. 
Also the error message does not indicate which topic actually failed (and the single quote is not closed ;) )
