TokenEndpoint handlers

As defined in TokenEndpoint.scala you can define these different kinds of authorization phases:

• authorization_code
• refresh_token
• client_credentials
• password

Note that when you make a POST request to your OAuth2 controller, you have to provide any of the above strings as is. For example:

$ wget -q -O - --post-data "grant_type=password&client_id=client1&client_secret=secret1&username=user1&password=pass1" http://localhost:9002/oauth2/access_token | python -mjson.tool
{
    "access_token": "MzE3YWI5MTUtZWEwNy00OTU1LTgyMTQtZmE2ZjBlMzQwYzYx",
    "expires_in": 3600,
    "refresh_token": "NmRmYjg1NzItMzc0YS00YTgzLTk0OWItMmFjNjQxM2U1NjFk",
    "scope": "",
    "token_type": "Bearer"
}
