Description

It appears if a KMS HTTP request is malformed, it could rejected by tomcat and a response is sent by KMSExceptionsProvider overriding Jersey's ExceptionMapper.

This behavior is okay, but in the logs we'll see an ERROR audit log, but nothing in kms.log (or anywhere else). This makes trouble shooting pretty painful, let's improve it.
