Configuration option to stop injected code from printing

[hderms]

I think it's helpful to print out things like:

Datadog env is not set
Datadog debug mode disabled

but we should at least provide an option to turn it off, given that a live app may have specific requirements about what is logged or in what format it is logged.

I have another use case when one of those messages sounds unclear. We provide APM settings via environment variables, like "DD_ENV", "DD_SERVICE", etc. APM already sets corresponding global tags, so I don't need to put them in sbt-datadog configuration. Are there plans to merge this PR so I can disable those messages?
