c94ca0e298
This patch adds a "--no-download" option to the "download" command. When given, all writing to disk is bypassed, while still actually downloading the data and validating etags. This can be handy when you're using the swift command-line client to test out a swift cluster and don't want client-side disk writing to be a bottle-neck (but you still want to know about any etag validation failures).
