Invalid metrics causing Datadog to log errors

[jeremy-degroot]

It seems that Dropwizard considers values of negative infinity to be valid and attempts to report them to Datadog, which considers them invalid and throws errors. My syslog is filling up with lines like the one below.

Dogstatsd: error parsing metrics: invalid metric value for "dp.consumer-node-metrics.request-size-max:-∞

Our workaround has been to implement a filter with a blacklist for metrics known to produce invalid values, but it would be nice if the reporter would handle this case internally.
