docs: Queries the given storage service for the {@link ServiceStats}.
  
  @param options
  A {@link BlobRequestOptions} 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 CloudBlobClient}).
  @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 {@link ServiceStats} for the given storage service
  @throws StorageException
  If a storage service error occurred.
