One-click online/rollback based on Rainbond

In the actual production environment, due to business upgrades, the code needs to be rolled back when an accident occurs. Rainbond implements a one-click rollback of the release version. For different business scenarios, the rollback function can be used to quickly roll back the application in the event of an accident. Roll back to the previous version to reduce business losses; Rainbond supports one-click quick rollback of a single component in the application, and also supports simultaneous rollback of multiple components in the application.
