Constructs a web request to clear all the messages in the queue. Sign the
web request with a length of -1L.

@param uri
A <code>URI</code> object that specifies the absolute URI to
the queue.
@param queueOptions
A {@link QueueRequestOptions} object that specifies execution options such as retry policy and timeout
settings for the operation. Specify <code>null</code> to use the request options specified on the
{@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 An <code>HttpURLConnection</code> configured for the specified
operation.

@throws IOException
@throws URISyntaxException
If the URI is not valid.
@throws StorageException
