Generic Webhook

Use the generic JSON ingest endpoint to generate log events from an external webhook.

e.g. you can set a Github webhook to send events to:

          
http://localhost:4000/logs/json?api_key=96cb6b91bb6af4454574e3c53b5749192cc59c19a8e806d86c4ee0b1a470c350&source=4887d8ed-29e0-41d6-b47e-196d23434c0c

Or send generic JSON events yourself.

          
    curl -X "POST" "http://localhost:4000/logs/json?source=4887d8ed-29e0-41d6-b47e-196d23434c0c" \
