Add logging of BoxAPIException.getResponse()

The requests are already logged: https://github.com/box/box-java-sdk/blob/05224c433d2a101a01959644674153df9542b711/src/main/java/com/box/sdk/BoxAPIRequest.java#L714

It would be very helpful when debugging to also have the error responses logged.

There should be a way to configure this on or off.

There would need to be a way to pass in an optional filter to remove PII from the exception text.
