[Kimchi-devel] [PATCH v3 3/4] storagevolume: Add download progress to task

The download operation can take a long time, so it's nice to have some way to track its current progress. Update the task's message with the number of bytes downloaded. The format is "<bytes downloaded>/<total bytes>". If the number of bytes cannot be read from the remote URL, <total bytes> will be "-".
