Add authentication and authorization

- I want to add a set of proper authentication API endpoints. 
- I will use the JWT module and others for the same
- API endpoints will be available after this implementation are below
  1.  ` /api/login`
  2.  ` /api/signup`
  3.  `/api/logout`
  4.  ` /api/protect`
  5.  `/api/forgotPassword`
  6.  `/api/reserPassword`
 
Thanks
