Support custom image tags for remote CLI images

As part of creating a distributable tarball or remote CLI
wrapper script, we must also be able to package an exact
version of docker image files to ensure compatibility
between the remote CLI tarball and the distributed ISO and
helm chart.

This change writes the desired image tag in a separate file
that can then be overwritten by the packaging script as
needed.
