Logs of span rate limiting should be write in INFO level in agent.log to detect it worked.

Instana manual explains as following;

> If you see logs like Suppressed spans due to high number of short or Discarded span due to queue overflow in the agent log, it means that the Java tracer experienced heavy load on span processing.

The description seems not to require user to set DEBUG mode, however it  is required actually.
If I set agent.log to Debug mode, I can detect it in the log. However it is not acceptable to set DEBUG mode permanently. 

It means users have no way of knowing that span rate limiting has been executed on production environment.

In the last discussion, ENG team said it was difficult to write in INFO log because suppressed messages will be a huge amount. However I disagree with this point. Since the suppressed messages are only output every 10 minutes. 

I expect to output it as an INFO level in agent.log.
