Add a CLI feature to roll a stuck change back. This is mostly useful for deployments performed using `--no-rollback`: if a failure occurs, the stack gets stuck in an `UPDATE_FAILED` state from which there are 2 options: - Try again using a new template - Roll back to the last stable state There used to be no way to perform the second operation using the CDK CLI, but there now is. `cdk rollback` works in 2 situations: - A paused fail state; it will initiating a fresh rollback. - A paused rollback state; it will retry the rollback, optionally skipping some resources. `cdk rollback --force` will look up all failed resources and continue skipping them until the rollback has finished.

cdk rollbackworks in 2 situations:CREATE_FAILED,UPDATE_FAILED).UPDATE_ROLLBACK_FAILED-- it seems there is no way to continue a rollback inROLLBACK_FAILEDstate).cdk rollback --orphan <logicalid>can be used to skip resource rollbacks that are causing problems.cdk rollback --forcewill look up all failed resources and continue skipping them until the rollback has finished.This change requires new bootstrap permissions, so the bootstrap stack is updated to add the following IAM permissions to the
deploy-actionrole:These are necessary to call the 2 CloudFormation APIs that start and continue a rollback.
