Deletes the queue if it exists, using the specified request options and operation context.

@param options
A {@link QueueRequestOptions} object that specifies any additional options for the request. Specifying
<code>null</code> will use the default request options from the associated service client (
{@link CloudQueueClient}).
@param opContext
An {@link OperationContext} object that represents the context for the current operation. This object
is used to track requests to the storage service, and to provide additional runtime information about
the operation.

@return A value of <code>true</code> if the queue existed in the storage service and has been deleted, otherwise
<code>false</code>.

@throws StorageException
If a storage service error occurred during the operation.
Deletes the queue if it exists using the specified request options and operation context .
