Publishing data to NATS

External clients can issue HTTP post requests to the default route / and publish messages directly to NATS.io, for example:

curl -s -H "Content-Type: application/json" \
-X POST -d '{"__subject":"CUSTOMER","account":"ACC-123456789","orders":"PO-123456789"}' \
http://localhost:8080/

This command will post the JSON data to the default route http://localhost:8080/, the nats-proxy server will read and parse the JSON data and will publish this data to NATS.io with a subject called CUSTOMER.
