Use @GenerateValue to automatically generate Id of Entities instead of UUID.randomUUID()

[kevin9foong]

Environment: v9-migration

Description of feature/enhancement Use @GeneratedValue for entities instead of using UUID.randomUUID() for sql entities.

For example, we should add a @GeneratedValue for the @Id field.

Justification

While there is a low chance of collision using UUID.randomUUID(), there is still a small chance of failure if the random UUID generated in teammates/src/main/java/teammates/sqllogic/core/DataBundleLogic.java persistDataBundle method.

Instead, a better practice might be to use @GeneratedValue annotation to generate a safe UUID for the respective entities such as Section, Student etc.

This would prevent a collision bug from ever occurring.
