This tries to remove the oldest metric of the buffer once we reach max capacity and replace it with the new metrics instead of discarding those.

I would really like to replace the exception based approach.
Thoughts?

Instead of remove we could use pool ( https://docs.oracle.com/javase/7/docs/api/java/util/concurrent/ArrayBlockingQueue.html#poll() ) which would allow us to log the discarded metric if we wanted, which I think we want, and doesn't throw exception if it's empty - returns null).
Thinking out loud, should we drop more then one metric?

we should, somehow, test the behaviour of trying to empty it when it's empty, more so if we keep the current exception based implementation for when it's empty
