Change default behaviour to skip deployments migration

To prevent issues with users not aware that deployments migration do not assert and fix compatibility, the following changes on the tool's default behaviour should be done:
1. when running in non interactive mode the configuration defaults to skip deployments migration
2. when running in interactive mode the executed migration task first asks if deployments migration should be skipped, alerting that compatibility is not asserted. Currently it just asks if all deployments should be migrated, the alert regarding compatibility is only seen on the tool's user guide.
