Recommended changes from review of #1568

- Make Resources an `interface{}` to support arbitrary yaml
- Remove `wwctl resource` as incompatible with arbitrary yaml
- Revert changes to host overlay templates
- Remove NFS mount options from warewulf.conf
- Replace NFS support / resource prefix with "fstab" resource
- Move resources to profiles
- Migrate warewulf.conf mounts to nodes.conf with `wwctl upgrade`
- Add documentation
