Policy output in nsjson format

[amckeown-blc]

Hi,

We currently have to run a python script to take the output from a Cloud Custodian policy which is in json format and put it into a ndjson format (newline delimited) in order for Amazon Athena to view it correctly.

This is fine and working, but is there a feature to do it in 0.9.48?

output_format: jsonlines

As this doesn't seem to work.
