Log exceptions thrown by API controllers

[elgris]

User story

As a developer I want controllers located in org.zalando.zmon.api log exceptions So that I have better visibility on problems

Explanation

Some controller classes already have @ExceptionHandlers enabled. For instance

public class AlertDefinitionsApi extends AbstractZMonController

Where AbstractZMonController defines a bunch of @ExceptionHandlers

However other controller classes don't have any exception handlers, so when the exception is thrown, error message is returned to the client, but not logged by ZMON controller.
