// The DeleteDBInstance action deletes a previously provisioned DB instance. When
// you delete a DB instance, all automated backups for that instance are deleted
// and can't be recovered. Manual DB snapshots of the DB instance to be deleted by
// DeleteDBInstance are not deleted. If you request a final DB snapshot the status
// of the Amazon RDS DB instance is deleting until the DB snapshot is created. The
// API action DescribeDBInstance is used to monitor the status of this operation.
// The action can't be canceled or reverted once submitted. When a DB instance is
// in a failure state and has a status of failed , incompatible-restore , or
// incompatible-network , you can only delete it when you skip creation of the
// final snapshot with the SkipFinalSnapshot parameter. If the specified DB
// instance is part of an Amazon Aurora DB cluster, you can't delete the DB
// instance if both of the following conditions are true:
//   - The DB cluster is a read replica of another Amazon Aurora DB cluster.
//   - The DB instance is the only instance in the DB cluster.
//
// To delete a DB instance in this case, first call the PromoteReadReplicaDBCluster
// API action to promote the DB cluster so it's no longer a read replica. After the
// promotion completes, then call the DeleteDBInstance API action to delete the
// final instance in the DB cluster.
