Observe all prefixes in metrics (#98)

Generate a metric even for watch prefixes that may never fire an event.
Current behavior is to not generate metric if no events.
https://github.com/IBM-Cloud/go-etcd-rules/blob/master/rules/etcd.go#L119-L130
This allows a query like  
```
count(data_etcd_operation_keys_sum{action="watch",method="rules-engine-watcher"}) by (prefix, method)
```
to show all the prefixes that are being watched, not just the ones that fire events.
