Logs filling up with "Nan" & "Infinite" errors (related to POMI)

[sskilbred]

The SDK is treating NaN and Infinites as an error. Since these values are rather common in some Prometheus environments, by using the Prometheus Open Metrics Integration the log files are polluted by this message and results in a too heavy log-load on certain containers. The issue was raised (as part of another issue) in nri-prometheus as well (newrelic/nri-prometheus#39).

Since the value is not an error in "Prometheus eyes", it shouldn't be treated as an error in "New Relic eyes" either. Instead of an error, treat it as a warning or information instead. If the log-level can be made configurable, that would even solve any objections anyone would have to this in the future.
