Title: Record the black/white list metrics

From `protocols.py`:

```python
def metricReceived(self, metric, datapoint):
if BlackList and metric in BlackList:
instrumentation.increment('blacklistMatches')
return
if WhiteList and metric not in WhiteList:
instrumentation.increment('whitelistRejects')
return
```

These metrics are instrumented, but are not written out in the `instrumentation.recordMetrics()` method. This adds them as common metrics so the results will actually be recorded.
