autoupdate_EndToEnd: Support legacy argument name.

The tree vs prod problem hits again, so this adds support for legacy
argument name ('source_image_uri') as fallback option.

Note that backward compatible API hacks can only be safely remove once
all release branches catch up with the corresponding control file
changes. Adding TODO comments accordingly.
