Let the Monitor intercept log4j

[paullatzelsperger]

The Apache Atlas client library comes with log4j (unfortunately), so we need to write a logging interceptor for it. The same thing has already been done for SLF4J (cf. MonitorProvider)

The Atlas library looks like it brings in half the internet in dependencies. Does it really help us or would a simple REST client suffice?

I think we can do without the API client, since it's only a wrapper around REST calls anyway.
