WIP: Compaction Scheduling

[shivansh02]

Description

Allows users to run borg compact after specified intervals. Added 2 columns to the profile model: compaction_on to check/uncheck scheduling, and compaction_weeks to set interval in weeks. Default interval set to 3 weeks.

Related Issue

Resolves #1718

Motivation and Context

Backup space usage is exploding for some people until they realize they have to run compact manually. This allows users to schedule running compact just like validation.

How Has This Been Tested?

Tested manually by setting compaction_cutoff to minutes instead of days in scheduler.py.
