fix: Removes connection limiting for the moment hawtio#272

* Trying to connection or rate limiting requests to the nginx server
  fails to provide a satisfactory working application

* Even rate limiting to 40 requests/second can kill the application by
  simply opening it in 5 different tabs

* Needs a far more sophisticated understanding of how to handle implementing
  such limits
