config.example.json and requirements.txt not up to date

[AlexandreDoneux]

You have not kept your requirements.txt up to date with the necessary python library (and their versions).

The config example also needs some changes :

• Add a "SQLALCHEMY_DATABASE_URI" default value. ex : "SQLALCHEMY_DATABASE_URI": "mysql://[email protected]/ictm_teaching". It will allow the user to use the create_db script without having to modify the config file.
• The saml attributes are not correct and make the app unusable. These should be :

"attributes": {
      "sn": "lastName",
      "email": "email",
      "givenName": "firstName",
      "uid": "uid"
      },

Not sure about the second point, will need to check that.
