Filter infinities and NaNs from the returned json

[jvshahid]

If the stored values, or the result of aggregation return infinity, the entire payload won't serialize properly. We need to filter these values from the response and may be print a warning in the log.

I don't suppose this will help when you have invalid data stored? Somehow I have a few series that ended up returning NAN's.

Using influxdb-cli for ease here. But this 500's over the HTTP interface as well. Nothing relevant in the log files.

Thanks.

@damm do you have any continuous queries ?

@jvshahid I have not setup any no.
