"""
Container enabled/disabled

Verify that a container can be enabled and disabled via configuration.
Tests the 'enabled' leaf functionality by:

1. Creating an enabled container and verifying it starts
2. Disabling the container and verifying it stops
3. Re-enabling the container and verifying it starts again

Uses operational datastore to verify container running status.
