Make node http server easier to configure

[enixsoft]

Currently, if I want to configure node's HTTP server inside AdonisJS, I can override the start method of the Ignitor (this code is from v5 but it applies to v6 as well):

new Ignitor(__dirname).httpServer().start((handler) => {
  const server: Server = require('http').createServer(handler)
  // Must be greater than AWS ALB idle timeout (60 seconds)
  server.keepAliveTimeout = 65000
  server.headersTimeout = 66000
  return server
})

Would it be a good idea to move settings like keepAliveTimeout to config/app.ts in the UserDefinedServerConfig and ServerConfig?
