Compute nodes post provisioning

Add mechanism to use latest image when there are multiple images with provided image name. Add user_data in nodes module to setup warewulf configuration, restart munge service, and restart slurmd service. Add null-resource compute-ops to register compute nodes into warewulf database. Define ohpc and ood static ip for private network Expose ohpc-instance id to use as trigger in null-resource Expose nodes id to use as trigger in null-resource Expose nodes network information for null-resource Update compute image name Update CRI_XCBC submodule to point to eesaan's repo which have ohpc-ops playbook.
