We need to extend the django user model to be able to retain relevant user information beyond username, email, and password.

This model needs to be extended for use in the base tom, but can also be generally extendable by developers.

• Create a user profile page #1102
• Securely store credentials in a TOM #1106
• Allow individual users to select from a group of visualization templates #868
• Tom Users who are not admin cannot change their own password #617
• Add UserAffiliation to the Base User Model #1104
• Add ability to remove yourself from a TOM Toolkit #1103
• Revisit and Revamp TOM Registration tom_registration#7
• Refactor Token Access for DRF API into extended User Model #1059
• Add integration points for apps to include partials on the User's profile page. #1105
• Update Data Service and Facility Apps to extend the User Model #1107

We will need to reconcile this with TOM_Registration
