Svet suggested that everywhere we should use 0 as a default null value for
the average enricher because we could often have situations where some of the
entities isn't up.
One way I can think of for doing this is if we change the argument
`valueToReportIfNoSensors` to `0` in Enrichers.java:268 but if we do so we have
to call `defaultValueForUnreportedSensors(null)` on the enricher to get to the
old behavior.
Basically we should consider how the null values will be treated especially
when binding a Scaling policy to aggregated sensor.
