docs: 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.
