post ansible staging of slurm.conf

From a discussion on integrating slurm.conf ood with the CRI_XCBC ansible scripts. The problem is the need to get the slurm.conf (and possibly some other files) moved from the provisioned ohpc master to the ood node. This file would ordinary be distributed by warewulf but ood is not provisioned by warewulf so the file distribution codes are not part of the ood image.

As a work around, it may be possible to use vagrant file staging tools to move the file between the nodes in a post ansible vagrant stanza. This issue explores that idea.

Note: the ideal solution, not explored here, would seem to be getting the warewulf agents installed on the ood node so that the slurm.conf and other key files are kept in sync over time.
