StartUploads endpoint Or expiry of stale Uploads entries.

It seems like the process for uploading should start with a StartUploads endpoint call. My thought for this is to reset any cruft entries in the Uploads table for this client. For example, suppose that a client had to restart uploads because of a master version change. (Note that these should actually be replaced or the upload just ignored). Or suppose that a client crashed, was deleted and re-installed midway through some uploads.

Another way to deal with this might be to expire entries in the Uploads table after they've been there for a period of time.

Another way would be to have a client delete their own stale entries from Uploads.

I'm attaching an example of an image that was stranded in the Shared Images Google Drive -- Haven't yet looked but I'm guessing it has an entry in the Upload table.
