This change updated SX to DX migration playbook to support IPsec when
migrated to DX. The migration playbook is supposed to run on System
Controller to migrate subclouds.
Test Plan:
PASS: In a DC system, define an overrides file, then run the migration
playbook in System Controller to migrate a SX subcloud, verify
the migration is successful, and verify IPsec is configured and
enabled in the migrated DX subcloud.
