When setting options, the existing configuration is now pre-populated into the options form.
When upgrading from versions earlier than 0.8.0, the configuration will be migrated to a new format to better support the new config flow. Configuration from YAML will no longer override the imported configuration, and should be deleted to avoid confusion. It is now possible to reconfigure and delete configuration from the UI even if it was imported from YAML in a version prior to 0.8.0.
