Is it possible to get a v4 release with the fix from #149 included?
Looking at the tags on [Docker Hub](https://hub.docker.com/r/prom/collectd-exporter/tags) I can only see master being updated. Should we use the two year old `v0.4.0` or is it safe to use `master`?
Simple enough changes
Having issues with PHPBrowser overwriting test output from WebDriver, a configurable prefix here aims to help prevent that, not sure if there's a better way though.
