Generate swagger specs of http eventsource in src/docs

[mastersilv3r]

The Problem

Currently Swagger UI opens up when the service is run but there is no way to export the docs.

The Solution

• [x] When a service boots up, store the swagger docs for http events in the src/docs/http-swagger.json
• [x] In the endpoints where authn: false, do not set "security": [ { "bearerAuth": [] } ]
