Lost of Rollback database

[WengerK]

💬 Is your feature request related to a problem? Please describe.

When using the automatic rollback feature, the system will:

1. Backup the database before anything

after :updated, "drupal:db:backup"

1. When something went wrong will run the rollback process (delete database and re-mount the previous dump

before :failed, "drupal:db:rollback"

1. then cleanup old database backup

  before :cleanup, "drupal:db:backup:cleanup"

During the drupal:db:rollback we have to (optionally) save the used database into a specific location, to prevent drupal:db:backup:cleanup to remove very important dump (before deploy crash it was the initial database state).

🧞 Describe the solution you'd like

Add a new configuration

set :keep_rollbacks, true

When use:

• Copy the dump into a new directory rollback before any command

We also may add a new task drupal:db:rollback:check that ensure the rollback dir exists
