Elastic's 'common schema' support?

[dragonpaw]

Elastic.co has a 'common schema' that they encourage, and it'd be nice if the format was understood by jl.

Spec: https://www.elastic.co/guide/en/ecs/current/index.html

Sample line:

{
  "service": { "name": "gunicorn" },
  "@timestamp": "2020-10-23T03:35:49.324754+00:00",
