Utilities/Release: Replace upload step with a "push" script

Replace the `upload_release.cmake` script with a `push.bash` script
that is more configurable from the command line and that does not
hard-code any destinations.  Instead of using `scp` to access
`cmake.org` directly, push the files atomically to a staging
directory from which another process will actually upload them.
