Improve ResourceUsage model fields and Command

[ARYAN-NIKNEZHAD]

We should enhance the model fields by improvements to ensure better functionality and alignment with current requirements.

Proposed Implementation for Resource Usage Monitoring

1. Enhance the ResourceUsage Model

• Add from_time and to_time fields to track the monitoring period.
• Include total_disk_read and total_disk_write to capture cumulative disk activity.
• Ensure fields are optional or have defaults for flexibility.

2. Update the Command to Support Time-Based Metrics

• Add --until argument to specify the end time for monitoring (format: HH:MM:SS).
• Add --interval_minutes argument to define the interval for metric collection.
• Calculate average CPU, memory, and disk usage over the specified period.
• Store cumulative network and disk activity (sent/received, read/write).

3. Example Command Usage

python manage.py collect_metrics --until "14:30:00" --interval_minutes 5
