There is another, more likely use case where we have a transport wrapper on
another message, and 1 topic split into many parsers as well. How can we
handle that?
Specifically -> Syslog (Many Msg types) -> kafka -> bolt -> Split per
message
I expect to add the ability for syslog parsing later, so set that aside.
The issue is we *will* have more than one use case wrt topics.
I am not going to say this PR needs to address it, but I would want us to
understand our path forward and minimize the churn.
It would be best if we did not have to redo this work when accounting for
that.
