Replace, remove or make configurable - printing non-log output to stdout/stderr (logo/banner in particular)

[andoks]

Currently I am getting the kapacitor ASCII logo printout classified as level "unknown" in our log database, which motivated me to do a quick search for fmt.Print, which there are a few of, that might seem like they can be encountered during operations (and not just testing etc).

Would it be ok to remove these or turning them into log statements of appropriate levels instead? Possibly behind a program flag/config option if keeping them in their current form is desirable for some reason?
