We have a limited amount of disk space on keymaster, and especially with as many releases as we have these days, we hit out-of-disk errors more often. IMHO there's no reason to keep the binaries (both signed and unsigned) on keymaster after we successfully upload back to stage. For Desktop, we should delete these directories after all verifications are finished. For Mobile, we should do it after the upload (because we have no verifications that run on keymaster afaik). Ideally, we'd move the directory to d:\signing-work\removed_binaries, too, but I don't think that's possible the cygwin shell will be in that directory, and Windows will complain

Mass move of bugs to Release Automation component.

We use the signing servers now, which clean up after themselves.
