Issue 2 create extended user models

[IvanParvanovski]

• As your application grows, incorporating a CustomUser model offers the adaptability to tailor the user system to meet the scalability demands unique to your use case.
• In Django, MEDIA_URL and MEDIA_ROOT settings handle user-uploaded media files by defining their URL and filesystem path. These settings facilitate the storage and serving of images or documents in your application.
• When implementing a custom user model in Django, initiating an initial migration is necessary to implement the corresponding changes in the database and correct links with the other tables such as django_admin_log.
