Downloads the queue's metadata and approximate message count value, 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 CloudQueue}).
@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.

@throws StorageException
If a storage service error occurred during the operation.
