Pauses the queue.
If a queue is paused then the system will stop dispatching tasks
until the queue is resumed via
[ResumeQueue][google.cloud.tasks.v2beta3.CloudTasks.ResumeQueue]. Tasks can
still be added when the queue is paused. A queue is paused if its
[state][google.cloud.tasks.v2beta3.Queue.state] is
[PAUSED][google.cloud.tasks.v2beta3.Queue.State.PAUSED].
