Review comment:
The above hard-codes the file suffix for PCAP-NG files. Is this suffix a
common standard? Or, should the suffix be part of the format configuration as
is done for, say, the `TextFormatPlugin`?

> Added pcapng-format support
> ---------------------------
>
> Key: DRILL-6179
> URL: https://issues.apache.org/jira/browse/DRILL-6179
> Project: Apache Drill
> Issue Type: New Feature
> Affects Versions: 1.13.0
> Reporter: Vlad
> Assignee: Vlad
> Priority: Major
> Labels: doc-impacting
> Fix For: 1.14.0
>
>
> The _PCAP Next Generation Dump File Format_ (or pcapng for short) [1] is an
> attempt to overcome the limitations of the currently widely used (but
> limited) libpcap format.
> At a first level, it is desirable to query and filter by source and
> destination IP and port, and src/dest mac addreses or by protocol. Beyond
> that, however, it would be very useful to be able to group packets by TCP
> session and eventually to look at packet contents.
> Initial work is available at
> https://github.com/mapr-demos/drill/tree/pcapng_dev
> [1] https://pcapng.github.io/pcapng/
