Create crowd.cfg.xml file while deploying Crowd on docker or K8s environment

We have a requirement to automate the Crowd deployment, to achieve this we need to pre-seed all the data in the crowd.cfg.xml file however Crowd docker image does not have a crowd.cfg.xml.j2 file to do this. We know due to product limitations it's not possible to create DB tables from scratch. But we would like to have an environment variable to still generate crowd.cfg.xml file when we have an empty Crowd schema prepared in the DB, so we can easily automate new Node creations on k8s deployment.
