Introduce the splunk sink.  There has been a transformer added so that messages
can be converted to a format that can be consumed by splunk.  There are several
types of events we can choose from so I chose the the most generic available
which was SplunkEvent.  For now all the data in the message is stored under the
data field.
Resolved merge conflicts
Removed name and id from the field of choices.  They did not add value.
