OpenShift compatible image that supports arbitrary user ids

How I fixed

To make the image compatible, I had to build my own. I had to set perms on the opal dir eg:

RUN chgrp -R 0 /some/directory && \ chmod -R g+rwX /some/directory

When I deployed, HOME was set to root, not opal.
This meant that the scripts in: https://github.com/permitio/opal/blob/master/packages/opal-common/opal_common/git_utils/
were trying to write/access the ssh_key from/to /.ssh instead of /opal/.ssh

There were NO error messages indicating this issue, I recommend adding more error handling to these scripts.

I fixed this issue by setting home to /opal.
