I think the intent behind this processor was to send data over a
connection, but not to read anything back. Essentially doing what PutSyslog and
PutSplunk are doing when in TCP mode.
That being said we could potentially have a header and footer, and
specifying only one of them would be the same as a single delimiter. I think
the idea behind the delimiter was more to separate the messages, typically
using new lines, but not wanting to hard code that.
Will have to review in more detail when I get a chance.
