Right now, a request like this (without Content-Type: application/json) results in 500 error + traceback:

# curl -s -k -X POST "https://172.20.0.2:11000/api/auth" -d "{\"username\":\"xxx\",\"password\":\"xxxx\"}" 
{
"status":
  "500 Internal Server Error",
"version":
  "3.2.2",
"detail":
  "The server encountered an unexpected condition which prevented it from fulfilling the request.",
"traceback":
  "Traceback (most recent call last):\n  File \"/usr/lib/python2.7/site-packages/cherrypy/_cprequest.py\", line 656, in respond\n

• Trying to parse an unsupperted content type can result in an exploit,
• The proper response according to HTTP 1.1 should be 416 - Unsupported Media Type (blame on client side) instead of 500 - Internal Server Error.
