Deletes a queue.
This command will delete the queue even if it has tasks in it.
Note: If you delete a queue, a queue with the same name can't be created
for 7 days.
WARNING: Using this method may have unintended side effects if you are
using an App Engine `queue.yaml` or `queue.xml` file to manage your queues.
Read
[Overview of Queue Management and
queue.yaml](https://cloud.google.com/tasks/docs/queue-yaml) before using
this method.
