feat: add django management command to purge app logs

[rohan-chaturvedi]

🔍 Overview

Secret access logs, particularly reads, can get to many thousands of entries quite quickly, especially when frequently polling for secrets.

💡 Proposed Changes

Add a django management command to safely purge logs older than a specified date. This util will delete all log events older than the spcified date (30 days be default), except for create events. The command can be run in the backend container with:

python manage.py purge_app_logs <organisation_name>

This will purge logs for all Apps in the given organisation that are older than 30 days.

Optionally, the number of days and a specific app_id can be supplied as arguments.

Purge logs for all apps older than 60 days:

python manage.py purge_app_logs <organisation_name> --days 60

Purge all logs for a specific app only

python manage.py purge_app_logs <organisation_name> --app_id <app_id>

Purge logs older than 60 days for a specific app

python manage.py purge_app_logs <organisation_name> --days 60 --app_id <app_id>
