Optional
The (FIFO) queue inside which the job request should wait for a free execution slot inside an engine. If null, the queue designated
as the default queue for this "application name" will be used.
Most of the time, this should be left to null. This parameter is only provided to avoid doing two API calls for a
single execution request (first enqueue, then change queue) when it is certain a specific queue will have to be used.
If there is no queue of this name, the enqueue method will throw a JqmInvalidRequestException
.
