[DJANGO] Support sensitive_variables decorators in integration

### Problem Statement

In the Django framework, a utility exists to declare that a variable is sensitive or not.

https://docs.djangoproject.com/en/3.2/_modules/django/views/decorators/debug/

Would it be possible to support this functionality in the integration directly?

### Solution Brainstorm

The SDK tries to read the sensitive_variables attribute on the functions it passes to add them to sensitive information not to be displayed clearly in sentry.
