Overrided the built-in (influxdb) writing function with a newer one from https://github.com/pradeepchhetri/riemann/blob/c56fbd0cbd13298993b96b9e02f9eca07495952e/src/riemann/influxdb.clj

Riemann's instructions on overriding built-in functions: http://riemann.io/howto.html#overriding-riemann-functions

The newer version of the function will allow you to programmatically compose series names. I'm making them in the pattern of host.service so I can query by series name in Grafana.
