Sunil Mohan Adapa 42d05bfe1f Use Django models to store variables
- Remove dependency on withsqlite and use Django models.
  This avoids depending on a module that is not available in PyPi.
  Withsqlite does not have Python3 support. It does not work when
  we choose a different database backend. Atleast partly duplicates
  what Django models are meant for.

- Check and update database schema on every run so that
  newly added modules can add tables and old ones can update.
