Support nanosecond (epoch nano) timestamp

[dannyk81]

Since fluentd supports nanosecond timestamp, could we extend this plugin to support epoch nano as well?

We have one source that currently set timestamp field to epoch nano, so at the moment we need to do a transformation to millisecs, would be nice if the plugin supported it out-of-the-box.

Currently, Elsaticsearch does not handle micro and nano-second precision.
But I think that it's worth handling micro or nano or pico or etc. precision timestamp.

See: elastic/elasticsearch#10005

I agree, Elasticsearch only handles millsecs but the plugin doesn't handles the cases where the timestamp key in the record is provided in nanoseconds.

We could simply convert the epoch nano to epoch milli and create the @timestamp from that, wdyt?

Actually, it should handle microseconds and nanoseconds (as well as seconds and millisecs)
